9.3 GnuTLS-extra Functions

These functions are only available in the GPL version of the library called gnutls-extra. The prototypes for this library lie in ‘gnutls/extra.h’.

gnutls_extra_check_version

Function: const char * gnutls_extra_check_version (const char * req_version)

req_version: the version to check

Check that the version of the gnutls-extra library is at minimum the requested one and return the version string; return NULL if the condition is not satisfied. If a NULL is passed to this function, no check is done, but the version string is simply returned.

gnutls_global_init_extra

Function: int gnutls_global_init_extra ( void)

This function initializes the global state of gnutls-extra library to defaults. Returns zero on success.

Note that gnutls_global_init() has to be called before this function. If this function is not called then the gnutls-extra library will not be usable.
