Telephony Phone Book Data Structures ^TOP^

This chapter describes the data structures used with the phone book service set of the telephony API.

TelPhbEntryType Struct ^TOP^

Purpose

The TelPhbEntryType structure describes a single entry in a phone book.

Declared In

TelephonyMgrTypes.h

Prototype

typedef struct _TelPhbEntryType {
   UInt16 phoneIndex;
   Char *fullName;
   UInt8 fullNameSize;
   Char *dialNumber;
   UInt8 dialNumberSize;
} TelPhbEntryType

Fields

→ phoneIndex

The index of the entry in the phone's phone book. This index is always zero-based.

The telephony manager is responsible for converting this index into the physical index in the phone, if required.

← fullName

A buffer into which the retrieved full name of the entry is stored.

This string is stored using the local character set of the Palm^™ handheld device. The telephony manager is responsible for converting the character set, if required.

Note that if this buffer is too small to contain the entire retrieved string, the string is truncated and the function using this structure generates a telErrBufferSize error.

fullNameSize

The size of the fullName string.

When the structure is used as an input parameter, this is the allocated size, in bytes, of the fullName buffer.

Upon return, this is the actual size of the string, including the null terminator character. If the fullName buffer is too small to contain all of the retrieved string, this field is assigned the entire length of the string, and the function using this structure generates a telErrBufferSize error.

← dialNumber

A buffer into which the retrieved telephone number of the entry is stored.

Note that if this buffer is too small to contain the entire retrieved string, the string is truncated, and the function using this structure generates a telErrBufferSize error.

dialNumberSize

The size of the dialNumber string.

When the structure is used as an input parameter, this is the allocated size, in bytes, of the dialNumber buffer.

Upon return, this is the actual size of the string, including the null terminator character. If the dialNumber buffer is too small to contain all of the retrieved string, this field is assigned the entire length of the string, and the function using this structure generates a telErrBufferSize error.

TelPhbGetAvailablePhonebooksType Struct ^TOP^

Purpose

The TelPhbGetAvailablePhonebooks() functions uses the TelPhbGetAvailablePhonebooksType structure to return a list of the phone books available on the phone.

Declared In

TelephonyMgrTypes.h

Prototype

typedef struct _TelPhbGetAvailablePhonebooksType {
   UInt16 count;
   UInt8 *phonebooksP;
} TelPhbGetAvailablePhonebooksType

Fields

↔ count

The number of entries in the array referenced by phonebooksP.

When the structure is used as an input parameter, this is the allocated size, in bytes, of the phonebooksP buffer. Upon return, this is the actual size of the retrieved data.

Upon return, this is the actual number of phone book IDs that could be retrieved. If the phonebooksP buffer is too small to contain all of the IDs, this field is assigned the actual count, and the function using this structure generates a telErrBufferSize error.

← phonebooksP

An array of retrieved phone book IDs. Each ID is one of the Phone Book Type Constants.

TelPhbGetEntriesType Struct ^TOP^

Purpose

The TelPhbGetEntries() function uses the TelPhbGetEntriesType structure to return a list of phone entries.

Declared In

TelephonyMgrTypes.h

Prototype

typedef struct _TelPhbGetEntriesType {
   UInt16 first;
   UInt16 count;
   TelPhbEntryType *entriesP;
} TelPhbGetEntriesType

Fields

→ first

The index of the first entry in the array referenced by entriesP.

count

When the structure is used as an input parameter, this is number of entries that you want retrieved.

Upon return, this is the actual number of entries that were retrieved.

← entriesP

An array of pointers to retrieved TelPhbEntryType structures.

TelPhbGetEntryCountType Struct ^TOP^

Purpose

The TelPhbGetEntryCount() function uses the TelPhbGetEntryCountType structure to return information about the entries in the currently selected phone book.

Declared In

TelephonyMgrTypes.h

Prototype

typedef struct _TelPhbGetEntryCountType {
   UInt16 slots;
   UInt16 count;
} TelPhbGetEntryCountType

Fields

← slots

The total number of entry slots available in the phone book.

count

The number of filled slots in the phone book.

TelPhbGetEntryMaxSizesType Struct ^TOP^

Purpose

The TelPhbGetEntryMaxSizes() function uses the TelPhbGetEntryMaxSizesType structure to return size information about the entries in the currently selected phone book.

Declared In

TelephonyMgrTypes.h

Prototype

typedef struct _TelPhbGetEntryMaxSizesType {
   UInt8 fullNameMaxSize;
   UInt8 dialNumberMaxSize;
} TelPhbGetEntryMaxSizesType

Fields

↔ ioTransIdP

Set the value of this parameter to NULL to cause the function to execute synchronously.

If this parameter is not NULL, the call executes asynchronously. Upon return from this function, this points to the transaction identifier associated with the asynchronous operation.

Synchronous Result

TelPhbSelectPhonebook()

TelPhbGetEntries Function ^TOP^

Purpose

Retrieve a range of entries from the currently selected phone book.

Declared In

TelephonyMgr.h

Prototype

Err TelPhbGetEntries(
   UInt16 iRefnum,

   UInt16 *ioTransIdP
)

Parameters

→ iRefnum

The telephony manager library reference number.

→ iAppId

The telephone application attachment identifier for your application.

↔ ioParamP

A pointer to a TelPhbGetEntriesType structure that is updated with the phone book entry information. The first entry retrieved is specified in the first field of this structure, which is zero-based; the number of entries retrieved is specified by the count field. Thus, the last entry retrieved is specified by:

ioParamP->first +
    ioParamP->count-1

Upon return, the count field of the structure is the number of entries that were actually retrieved.

The entriesP field of this structure is a buffer that you allocate to contain the required number of pointers. Each pointer references a TelPhbEntryType structure that you must also preallocate.

On input, the fullNameSize and dialNumberSize fields of this structure specify the allocated sizes of the fullName and dialNumber buffers. Upon return, the fullNameSize and dialNumberSize fields specify the actual sizes of the buffers, even if a string was truncated to fit into the buffer.

If this parameter is not NULL, the call executes asynchronously. Upon return from this function, this points to the transaction identifier associated with the asynchronous operation.

Synchronous Result

Returns errNone if the function was successful or returns an error code if not successful.

Asynchronous Result

The following fields are updated in the TelEventType event that is sent when the operation completes:

returnCode

errNone upon success or an error code upon failure

transId

The transaction ID of the operation.

paramP

Points to the TelPhbGetEntriesType structure passed to this function in the ioEntriesP parameter.

functionId

kTelPhbGetEntriesMessage

Comments

The phone book information is stored into the TelPhbEntryType structures that you preallocate and refer to in the entriesP field of the TelPhbGetEntriesType referenced by the ioParamP parameter.

If any buffer in any of the TelPhbEntryType structures is too small, the string intended for that buffer is truncated, and this function returns the telErrBufferSize error. In any case, the fullNameSize and dialNumberSize fields of each TelPhbEntryType structure contain the actual size of their respective strings.

If any entries in the specified range are empty, the entry is not retrieved, and the count value in the structure is updated.

Before using this function, you should verify that it is available by calling the TelIsPhbServiceAvailable() macro.

Compatibility

Implemented only if 4.0 New Feature Set is present.
