Detailed Description

Version information.

Version information may be used to check the library version at compile-time, using macros, or at run-time, using constants.

Function Documentation

const char* stp_check_version ( unsigned int  required_major,
unsigned int  required_minor,
unsigned int  required_micro 
)

Check whether the library provides the requested version.

Parameters:
required_majorthe minimum major revision.
required_minorthe minimum minor revision.
required_microthe minimum micro revision.
Returns:
NULL if the version matches, or else a description of the error if the library is too old or too new.
