dosmktemp

Purpose

     Creates a DOS temporary file.

Library

     DOS Services Library (libdos.a)

Syntax

     #include <dos.h>

     DOSFILE dosmktemp ( )

Description

     The dosmktemp  subroutine creates  and opens  a temporary
     file.  The  file is  open for  reading and  writing.  The
     access permission  flags are  set so  that the  owner has
     read-write permission and all others have no permission.

     The file  is created  in the /tmp  directory with  a name
     that includes the process ID of the running process and a
     serial number.   The /tmp directory  does not need  to be
     accessible through the DOS file system configuration.

Return Value

     Upon  successful completion,  a non-NULL  file handle  is
     returned.  This handle is to  be used in subsequent oper-
     ations.

     If  the dosmktemp  subroutine fails,  -1 is  returned and
     doserrno is set to indicate the error.
