dosclose

Purpose

     Closes a DOS file.

Library

     DOS Services Library (libdos.a)

Syntax

     #include <dos.h>

     int dosclose (dosfile)
     DOSFILE dosfile;

Description

     The dosclose subroutine closes the file descriptor speci-
     fied by the dosfile parameter.

     The dosfile parameter is  a file descriptor obtained from
     a dosopen, doscreate, or dosdup subroutine.

     Warning:   DOS files  are  not implicitly  closed when  a
     process terminates.   You must  explicitly close  all DOS
     files or you may lose data.

Return Value

     Upon successful completion, a value of 0 is returned.  If
     the dosclose subroutine fails, a  value of -1 is returned
     and doserrno is set to indicate the error.
