#include "sfluid.h" int set_uid_root (void)
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().
{ #if (defined (DOES_UID)) # if (defined (__UTYPE_HPUX)) return (setuid (get_uid (EFFECTIVE_ID))); # elif (defined (__OS2__)) /* OS/2 only supports one UID */ return (0); # elif (defined (__VMS__)) /* No setuid under OpenVMS */ return (0); # else return (seteuid (get_uid (EFFECTIVE_ID))); # endif #else return (0); #endif }
