CLOSE(2)            Linux Programmer's Manual            CLOSE(2)
+

+
+
NAME
+
       close - close a file descriptor
+
+
SYNOPSIS
+
       #include <unistd.h>
+
+       int close(int fd);
+
+
DESCRIPTION
+
       close  closes  a  file  descriptor,  so  that it no longer
+       refers to any file and may be reused.
+
+       If fd is the last copy of a particular file descriptor the
+       resources  associated  with  it are freed; for example any
+       locks held are removed and if the descriptor was the  last
+       reference  to  a  file which has been removed using unlink
+       the file is deleted.
+
+
RETURN VALUE
+
       close returns zero on success, or -1 if an error occurred.
+
+
ERRORS
+
       EBADF  fd isn't a valid open file descriptor.
+
+
CONFORMING TO
+
       SVID, AT&T, POSIX, X/OPEN, BSD 4.3
+
+
NOTES
+
       Not  checking  the  return  value of close is a common but
+       nevertheless  serious  programming  error.   File   system
+       implementations  which  use techniques as ``write-behind''
+       to increase performance may lead to  write(2)  succeeding,
+       although  the  data  has  not been written yet.  The error
+       status may be reported at a later write operation, but  it
+       is  guaranteed  to  be  reported on closing the file.  Not
+       checking the return value when closing the file  may  lead
+       to  silent  loss of data.  This can especially be observed
+       with NFS and disk quotas.
