NAME
door_ucred - return credential information associated with
the clientSYNOPSIS

#include
int door_ucred(ucred_t **info);
DESCRIPTION
The door_ucred() function returns credential information
associated with the client, if any, of the current door invocation.When successful, door_ucred() writes a pointer to a user
credential to the location pointed to by info if that loca-
tion was previously NULL. If that location was non-null,
door_ucred() assumes that info points to a previously allo-
cated ucred_t which is then reused. The location pointed to
by info can be used multiple times before being freed. Thevalue returned in info must be freed using ucred_free(3C).
The resulting user credential includes information about the effective user and group ID, the real user and group ID, all privilege sets and the calling PID. The credential information associated with the client refersto the information from the immediate caller, not neces-
sarily from the first thread in a chain of door calls.RETURN VALUES
Upon successful completion, door_ucred() returns 0. Other-
wise, -1 is returned and errno is set to indicate the error,
in which case the memory location pointed to by the info argument is unchanged.ERRORS
The door_ucred() function will fail if:
EAGAIN The location pointed to by info was NULL and allo-
cating memory sufficient to hold a ucred failed. EFAULT The address of the info argument is invalid.SunOS 5.11 Last change: 22 Mar 2005 1
