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



NAME
     Pfork - create a copy of the current process

SYNOPSIS
     WORD Pfork();

DESCRIPTION
     Pfork creates a copy of the current process. The child  (the
     new process created) inherits a copy of the parent's address
     space, not the parent's original memory, and so  changes  to
     variables  in the child do not affect the parent in any way.
     The new process begins execution  with  an  apparent  return
     from the Pfork call.

RETURNS
     0 in the child

     The new process id (a positive number), in the parent.

     ENSMEM if there is not enough memory to create the new  pro-
     cess.

SEE ALSO
     Pexec(2), Pvfork(2)

BUGS
     If the parent is in supervisor mode when this call is  made,
     the  child  will be started in user mode anyway; thus, it is
     strongly recommended that this call be made only  from  user
     mode.

     The current implementation of Pfork acts like Pvfork in that
     the  parent  is  suspended  until  the child either exits or
     overlays itself with Pexec mode 200. Do  not  rely  on  this
     behavior, as it will be changed in future versions of MiNT.
