TipcMsgAppendInt8Array

T_BOOL TipcMsgAppendInt8Array(msg, int8_array_data, array_size) 
T_IPC_MSG msg; 
T_INT8 *int8_array_data; 
T_INT4 array_size;

Arguments

Return Values

TRUE if the field was successfully appended to the message, FALSE otherwise.

Diagnostics

If TipcMsgAppendInt8Array fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg was null or int8_array_data was null

T_ERR_READ_ONLY — the message was marked read-only. This happens if the message is a field in another message.

T_ERR_MSG_INVALID — msg was not a valid message

T_ERR_VAL_TOO_SMALL — array_size was negative

Description

TipcMsgAppendInt8Array appends an eight-byte integer array (INT8_ARRAY) field containing int8_array_data to the end of a message’s data. TipcMsgAppendInt8Array makes a copy of the array data.

Caution

Eight-byte integers are not available as native integer data types on all platforms.
