rpc_gss_getcred(3NSL)Networking Services Library Functionrpc_gss_getcred(3NSL)NAMErpc_gss_getcred - get credentials of client
SYNOPSIS
#include <rpc/rpcsec_gss.h>
bool_t rpc_gss_getcred(struct svc_req *req, rpc_gss_rawcred_ t **rcred,
rpc_gss_ucred **ucred, void **cookie);
DESCRIPTIONrpc_gss_getcred() is used by a server to fetch the credentials of a
client. These credentials may either be network credentials (in the
form of a rpc_gss_rawcred_t structure) or UNIX credentials.
For more information on RPCSEC_GSS data types, see the rpcsec_gss(3NSL)
man page.
PARAMETERS
Essentially, rpc_gss_getcred() passes a pointer to a request (svc_req)
as well as pointers to two credential structures and a user-defined
cookie; if rpc_gss_getcred() is successful, at least one credential
structure is "filled out" with values, as is, optionally, the cookie.
req Pointer to the received service request. svc_req is
an RPC structure containing information on the context
of an RPC invocation, such as program, version, and
transport information.
rcred A pointer to an rpc_gss_rawcred_t structure pointer.
This structure contains the version number of the RPC‐
SEC_GSS protocol being used; the security mechanism and
QOPs for this session (as strings); principal names for
the client (as a rpc_gss_principal_t structure) and
server (as a string); and the security service
(integrity, privacy, etc., as an enum). If an applica‐
tion is not interested in these values, it may pass
NULL for this parameter.
ucred The caller's UNIX credentials, in the form of a pointer
to a pointer to a rpc_gss_ucred_t structure, which
includes the client's uid and gids. If an application
is not interested in these values, it may pass NULL for
this parameter.
cookie A four-byte quantity that an application may use in any
manner it wants to; RPC does not interpret it. (For
example, a cookie may be a pointer or index to a struc‐
ture that represents a context initiator.)

RETURN VALUESrpc_gss_getcred() returns TRUE if it is successful; otherwise, use
rpc_gss_get_error() to get the error associated with the failure.
