#include "sfluid.h"
int
set_uid_root (void)

Synopsis

This function can be used by 'setuid' programs; i.e. programs that run under a fixed uid such as 'root'. Typically such programs need to access root resources, but user data files. To do this they must switch between the 'root' uid and the 'user' uid. This function switches back to the root user id. Use set uid user() to switch to the 'user' uid. See also: set gid user() and set gid root().
