rpc_gss_get_error() fetches an error code when an RPCSEC_GSS routine fails.

rpc_gss_get_error() uses a rpc_gss_error_t structure of the following form:

typedef struct {
int	rpc_gss_error;		RPCSEC_GSS error	
int	system_error;		system error   
} rpc_gss_error_t;

Currently the only error codes defined for this function are

#define RPC_GSS_ER_SUCCESS		0	/* no error */
#define RPC_GSS_ER_SYSTEMERROR	1	/* system error */

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

error

A rpc_gss_error_t structure. If the rpc_gss_error field is equal to RPC_GSS_ER_SYSTEMERROR, the system_error field will be set to the value of errno.

Unless there is a failure indication from an invoked RPCSEC_GSS function, rpc_gss_get_error() does not set error to a meaningful value.
