pcGetProcAddress(3)
NAME
pcGetProcAddress -- Gets the address of an extension function.
Synopsis
PCvoidp pcGetProcAddress(
PCstring funcName
);
Parameters
funcName The name of an extension entry point.
Returns
NULL if the function is not implemented in this version of the Library; otherwise, the address of
the function.
Description
This function returns a pointer to a function that is defined by an extension to the Library. If the
entry point does not exist in the implementation, this function returns NULL.
Applications must make a runtime check for the existence of the extension before trying to use
the returned function pointer. In the case where the entry point is provided by a library other
than the Library, pcGetProcAddress might return a non-NULL value; however, the extension
would not be defined.
