Alphabetical Transaction Function Reference

This chapter provides a comprehensive, alphabetically-ordered reference to the TCAP transaction API functions. A prototype of each function is shown with the function description, details of all arguments, and return values. Some of the fields in the function definition include: Prototype The prototype is shown followed by a listing of the function's arguments. NMS Communications data types include: · U8 · S16 · DWORD · Bool · 8-bit unsigned · 16-bit signed · 32-bit unsigned · 8-bit unsigned If a function argument is a data structure, the complete data structure is defined. Note: Not all parameters are applicable to both ANSI and ITU-T (CCITT) networks. Return Values The return value for a function is either TCAP_SUCCESS or an error code. For asynchronous functions, a return value of TCAP_SUCCESS (zero) indicates the function was initiated; subsequent events indicate the status of the operation. Note: Use of the TCAP API requires the prior installation of the SCCP layer package, particularly the sccpapi.h file, which defines some data structures and constants required for TCAP applications.

Prototype	The prototype is shown followed by a listing of the function's arguments. NMS Communications data types include:
	· U8 · S16 · DWORD · Bool	· 8-bit unsigned · 16-bit signed · 32-bit unsigned · 8-bit unsigned
	If a function argument is a data structure, the complete data structure is defined. Note: Not all parameters are applicable to both ANSI and ITU-T (CCITT) networks.
Return Values	The return value for a function is either TCAP_SUCCESS or an error code. For asynchronous functions, a return value of TCAP_SUCCESS (zero) indicates the function was initiated; subsequent events indicate the status of the operation.
