_cred_info

Structure that describes user and group credentials

Synopsis:

#include <sys/neutrino.h>

struct _cred_info {
    uid_t      ruid;
    uid_t      euid;
    uid_t      suid;
    gid_t      rgid;
    gid_t      egid;
    gid_t      sgid;
    uint32_t   ngroups;
    gid_t      grouplist[__NGROUPS_MAX];
};

Description:

The _cred_info structure describes user and group credentials. The members include:

uid_t ruid: The real user ID.
uid_t euid: The effective user ID.
uid_t suid: The saved user ID.
gid_t rgid: The real group ID.
gid_t egid: The effective group ID.
gid_t sgid: The saved group ID.
uint32_t ngroups: The number of groups actually stored in grouplist.
gid_t grouplist[NGROUPS_MAX]: The supplementary group IDs.

This structure is defined with a fixed-sized grouplist field for backward compatibility, but it's often used with an arbitrary-sized grouplist array.
