NAME
       rpc_gss_get_mechanisms, rpc_gss_get_mech_info, rpc_gss_get_versions, rpc_gss_is_installed - get information on mechanisms and RPC version

SYNOPSIS
       #include <rpc/rpcsec_gss.h>

       char **rpc_gss_get_mechanisms();

       char **rpc_gss_get_mech_info(char *mech, rpc_gss_service_t *service);

       bool_t rpc_gss_get_versions(u_int *vers_hi, u_int *vers_lo);

       bool_t rpc_gss_is installed(char *mech);

DESCRIPTION
       These "convenience functions" return information on available security mechanisms and versions of  RPCSEC_GSS .

       rpc_gss_get_mechanisms()        Returns a list of supported security mechanisms as a null-terminated list of character strings.

       rpc_gss_get_mech_info()         Takes two arguments:  an ASCII string representing a mechanism type, for example, kerberosv5, and a pointer
                                       to a rpc_gss_service_t enum. rpc_gss_get_mech_info() will return NULL upon error or if no /etc/gss/qop file
                                       is  present. Otherwise, it returns a null-terminated list of character strings of supported Quality of Pro-
                                       tections (QOPs) for this mechanism. NULL or empty list implies only that the default QOP is  available  and
                                       can be specified to routines that need to take a QOP string parameter as NULL or as an empty string.

       rpc_gss_get_versions()          Returns the highest and lowest versions of  RPCSEC_GSS supported.

       rpc_gss_is_installed()          Takes an ASCII string representing a mechanism, and returns TRUE if the mechanism is installed.

PARAMETERS
       Information on RPCSEC_GSS data types for parameters may be found on the rpcsec_gss(3NSL) man page.

       mech            An ASCII string representing the security mechanism in use.  Valid strings may also be found in the /etc/gss/mech file.

       service         A pointer to a rpc_gss_service_t enum, representing the current security service (privacy, integrity, or none).

       vers_hi         The highest and lowest versions of RPCSEC_GSS supported.
       vers_lo

FILES
       /etc/gss/mech           File containing valid security mechanisms

       /etc/gss/qop            File containing valid QOP values
