setregid(2) System Calls Manual setregid(2)Name
setregid - set real and effective group ID
Syntax
setregid(rgid, egid)
int rgid, egid;
Description
The real and effective group ID's of the current process are set to the arguments.
Supplying a value of -1 for either the real or effective group ID forces the system to substitute the current ID for the -1 parameter.
Environment
BSD
If the process is superuser, or and matches with the real group ID, the effective group ID, or the saved set-group-id (as described in ),
then the real, effective, and saved set-group-id are set to and respectively.
POSIX
SYSTEM-FIVE
When your program is compiled in POSIX or SYSTEM-FIVE mode, the following semantics apply when using the function.
If the process is the superuser, the real, effective, and saved set-group-id (as described in ) are set to and respectively.
If the process is not the superuser, but the and matches the real group ID, the effective group ID (only in SYSTEM-FIVE and BSD environ-
ment), or the saved set-group-id, then the effective ID is set to The real group ID and the saved set-group-id are left unchanged.
Return Values
Upon successful completion, a value of zero (0) is returned. Otherwise, a value of -1 is returned, and errno is set to indicate the error.
Diagnostics
[EPERM] The current process is not the superuser and the and specified does not match with the real group ID or the effective group
ID (only in SYSTEM-FIVE and BSD environment) or the saved set-group-id.
