Psetpgrp()                                                           GEMDOS

Syntax

LONG Psetpgrp( pid, newgrp )
WORD pid, newgrp;

Function      Psetpgrp() sets the process group ID of the specified
              process.

Opcode        270 (0x10E)

Availability  This function is available under all MiNT versions
              integrated with MultiTOS.

Parameters    The process group ID of the process with process ID pid will
              have its process group ID changed to newgrp if the calling
              process has the same user ID or is the parent of the
              specified process. If pid is 0, the process group ID of the
              current process is sent. If newgrp is 0, the process group
              ID is set to equal the processes' (not the callers' unless
              pid is also set to 0) process ID.

Binding       move.w   newgrp,-(sp)
              move.w   pid,-(sp)
              move.w   #$10E,-(sp)
              trap     #1
              addq.l   #6,sp

Return Value  Psetpgrp() returns newgrp if successful or a negative GEMDOS
              error code otherwise.
