SYNOPSIS

setreuid(ruid, euid)
int ruid, euid;
 

DESCRIPTION

The real and effective user ID's of the current process are set according to the arguments. If ruid or euid is -1, the current uid is filled in by the system. Unprivileged users may change the real user ID to the effective user ID and vice-versa; only the super-user may make other changes.  

RETURN VALUE

Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.  

ERRORS

[EPERM]
The current process is not the super-user and a change other than changing the effective user-id to the real user-id was specified.
