Using the function reference

This section provides an alphabetical reference to the TX SWI functions. A typical function includes:

Prototype

The prototype is shown followed by a listing of the function arguments. Data types include:

  • U8 (8-bit unsigned)

  • S8 (8-bit signed)

  • U16 (16-bit unsigned)

  • S16 (16-bit signed)

  • U32 (32-bit unsigned)

  • S32 (32-bit signed)

 

If a function argument is a data structure, the complete data structure is defined.

Note: Some parameters are not applicable to both ANSI and ITU-T (CCITT) networks.

Return values

The return value for a function is either SUCCESS or an error code. SUCCESS (zero) indicates the function was initiated. Subsequent events indicate the status of the operation.
