CLOSE(II)                    8/5/73                     CLOSE(II)







NAME

     close  -  close a file



SYNOPSIS

     (close = 6.)

     (file descriptor in r0)

     sys close



     close(fildes)





DESCRIPTION

     Given a file descriptor  such  as  returned  from  an  open,

     creat,  or  pipe  call, close closes the associated file.  A

     close of all files is automatic on exit, but since processes

     are  limited  to  15  simultaneously  open  files,  close is

     necessary for programs which deal with many files.



SEE ALSO

     creat (II), open (II), pipe (II)



DIAGNOSTICS

     The error bit (c-bit) is set for an unknown file descriptor.

     From C a -1 indicates an error, 0 indicates success.
