Psetreuid()                                                          GEMDOS

Syntax

LONG Psetreuid( ruid, euid )
WORD ruid;
WORD euid;

Function      Psetreuid() sets the real and/or effective user id for the
              calling process.

Opcode        334 (0x014e)

Availability  Available when a 'MiNT' cookie with a version of at least
              1.12 exists.

Parameters    ruid specifies the new real user id and euid specifies
              the new effective user id for the calling process. If either
              argument is -1, only the other gets changed.

Binding       move.w  euid,-(sp)
              move.w  ruid,-(sp)
              move.w  #$014e,-(sp)
              trap    #1
              addq.l  #6,sp

Return Value  Psetreuid() returns E_OK on success or a negative GEMDOS
              error code otherwise.

Caveats       Setting user ids needs root privileges.

Comments      This call is often used by daemon processes to downgrade
              their privileges to user level.
