door_ucred - return credential information associated with the client
cc -mt [ flag... ] file... [ library... ] #include <door.h> int door_ucred(ucred_t **info);
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 location was previously NULL. If that location was non-null, door_ucred() assumes that info points to a previously allocated ucred_t which is then reused. The location pointed to by info can be used multiple times before being freed. The value 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 refers to the information from the immediate caller, not necessarily from the first thread in a chain of door calls.
Upon successful completion, door_ucred() returns 0. Otherwise, -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.
The door_ucred() function will fail if:
EAGAIN
EFAULT
EINVAL
ENOMEM
