Function Documentation

◆ rc_mksid()

char * rc_mksid ( void )

Generate a "unique" session-ID string.

Deprecated: This function is retained only for source compatibility with freeradius-client and radiusclient-ng. It returns a pointer to a static non-reentrant buffer that is overwritten on each call, making it unsafe in multi-threaded applications. Use snprintf into your own buffer instead:

char sid[15];

snprintf(sid, sizeof(sid), "%08lX%04X", (unsigned long)time(NULL), getpid());

Returns: pointer to a static buffer containing the ID string; overwritten by subsequent calls.
