setregid
setregid(2) System Calls Manual setregid(2) NAME
setregid - sets the real and effective group IDs SYNOPSIS
DESCRIPTION
sets the real and effective group IDs of the calling process. Only a privileged process can set the real group ID and/or the effective group ID to any valid value. A nonprivileged process can set the real group ID to the saved set-group-ID from one of the exec family of functions, or the effective group ID to either the saved set-group- ID or the real group ID. Any supplementary group IDs of the calling process remain unchanged. Argument rgid is the read group ID value to be set with. If rgid is set to the real group ID is not be changed. Argument egid is the effective group ID value to be set with. If egid is set to -1, the effective group ID is not changed. The real and effective group IDs may be set to different values in the same call. Security Restrictions Some or all of the actions associated with this system call require the privilege (CHSUBJIDENT). Processes owned by the superuser will have this privilege. Processes owned by other users may have this privilege, depending on system configuration. See privileges(5) for more information about privileged access on systems that support fine-grained privileges. RETURN VALUE
Upon successful completion is set to Otherwise, errno is set to indicate the type of error and neither group IDs are changed. ERRORS
is set to one of the following values if the corresponding condition is detected. The value of the rgid or egid argument is invalid or out-of-range. The process does NOT have all the appropriate privileges other than to change the real group ID to the saved set-group-ID, or to change the effective group ID to either the real group ID or the saved set-group-ID.
