#include <sasl/sasl.h> int sasl_getpath_t(void *context, char ** path);
sasl_getpath_t is used if the application wishes to use a different location for the SASL mechanism drivers (the shared library files). If this callback is not used SASL will either use the location in the environment variable SASL_PATH or /usr/lib/sasl2 by default.
SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_OK indicates success.
