Description
The subroutine sets both the real and effective user ID of the current process to the ID specified. Likewise, the subroutine sets the real
and effective group ID of the current process to the ID specified.
The subroutine sets the effective user ID of the current process, while the subroutine sets the effective group ID of the current process.
The subroutine sets the real user ID of the current process, while the subroutine sets the real group ID of the current process.
These calls are only permitted to the super-user or if the argument is the real or effective ID.
Environment
POSIX
SYSTEM_FIVE
When your program is compiled in POSIX or System V mode the following semantics apply when using the or functions:
If the process is the super-user the real, effective, and saved set (as described in user/group ID are set to uid.
If the process is not the super-user, but uid is equal to the real or the saved set user/group ID, the effective user/group ID is set to
uid. The real and saved set user/group ID remain unchanged.
POSIX
In POSIX mode, the function returns a value of type uid_t. The function returns a value of type gid_t.
Return Values
Zero is returned if the user ID or group ID is set; -1 is returned otherwise.
