NAME
rpc_gss_get_error() — get error codes on failure
SYNOPSIS
#include <rpc/rpcsec_gss.h>
bool_t rpc_gss_get_error(rpc_gss_error_t *error);
DESCRIPTION
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 */
PARAMETERS
For additional information on
RPCSEC_GSS
data types for parameters, see the
rpcsec_gss(3N)
manpage.
- 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.
MULTITHREAD USAGE
- Thread Safe:
Yes
- Cancel Safe:
Yes
- Fork Safe:
No
- Async-cancel Safe:
No
- Async-signal Safe:
No
These functions can be called safely in a multithreaded environment.
They may be cancellation points in that they call functions that are
cancel points.
In a multithreaded environment, these functions are
not safe to be called by a child process after
fork()
and before
exec().
These functions should not be called by a multithreaded application
that supports asynchronous cancellation or asynchronous signals.
RETURN VALUE
Unless there is a failure indication from an invoked
RPCSEC_GSS
function,
rpc_gss_get_error()
does not set
error
to a meaningful value.
Notes
Only system errors are currently returned.
