MTP 3 Service Alphabetical Function Reference

This chapter provides a comprehensive, alphabetically-ordered reference to the MTP 3 service 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 · U32 · 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. Return Values The return value for a function is either MTP3_SUCCESS or an error code. For asynchronous functions, a return value of MTP3_SUCCESS (zero) indicates the function was initiated; subsequent events indicate the status of the operation.

Prototype	The prototype is shown followed by a listing of the function's arguments. NMS Communications data types include:
	· U8 · S16 · U32 · 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.
Return Values	The return value for a function is either MTP3_SUCCESS or an error code. For asynchronous functions, a return value of MTP3_SUCCESS (zero) indicates the function was initiated; subsequent events indicate the status of the operation.
