Psetuid(2)                Oct. 1, 1991                 Psetuid(2)



NAME
     Psetuid, Psetgid - change a process' user or group id

SYNOPSIS
     WORD Psetuid(WORD uid);
     WORD Psetgid(WORD gid);

DESCRIPTION
     Psetuid sets the user id of  the  current  process  to  uid,
     which  must  be  a number between 0 and 255 inclusive.  This
     function call will fail if the user id is not already 0,  so
     once a process' user id is set it is fixed.  Psetuid returns
     uid, if the call is successful, and EACCDN  if  the  process
     does  not have the authority to change its own user id (i.e.
     if its effective user id is not 0 at the time of the call).

     Similarly, Psetgid sets the group id of the current  process
     to gid, which again must be between 0 and 255. The new group
     id gid is returned if successful, and EACCDN is returned  if
     permission to change groups is denied.

BUGS
     Security in MiNT is a joke; don't rely  on  these  calls  to
     actually  protect  you from anything, it's more for informa-
     tional purposes.
