 RPC_GSS_GETCRED 3NSL "September 22, 2020"
 NAME
rpc_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);


 DESCRIPTION
rpc_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 RPCSEC_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
application 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
structure that represents a context initiator.) See also
rpc_gss_set_callback(3NSL).


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