# Using the MCC SDP function reference

The function reference describes each MCC SDP function and displays its prototype and return values. The function reference provides additional details, when necessary, and also provides a code sample for the function.

Prototype | The prototype is followed by a listing of the function's arguments. If a function uses a structure, the structure is listed as an argument.
Return values | A return value of MCCSDP_OK indicates that the function completed successfully. Other possible return values are listed in the description of each individual call.
Example | Example functions are taken from sample application programs shipped with the product. The notation /* ... */ indicates additional code that is not shown.
