This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. For more information about the manual page format, see the manual page for manpages(5). |
FCLOSE(3) BSD Library Functions Manual FCLOSE(3) NAME fclose -- close a stream LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdio.h> int fclose(FILE *stream); DESCRIPTION The fclose() function dissociates the named stream from its underlying file or set of functions. If the stream was being used for output, any buffered data is written first, using fflush(3). RETURN VALUES Upon successful completion 0 is returned. Otherwise, EOF is returned and the global variable errno is set to indicate the error. In either case no further access to the stream is possible. ERRORS The fclose() function may also fail and set errno for any of the errors specified for the routines close(2) or fflush(3). NOTES The fclose() function does not handle NULL arguments; they will result in a segmentation violation. This is intentional - it makes it easier to make sure programs written under FreeBSD are bug free. This behaviour is an implementation detail, and programs should not rely upon it. SEE ALSO close(2), fflush(3), fopen(3), setbuf(3) STANDARDS The fclose() function conforms to ISO/IEC 9899:1990 (``ISO C90''). BSD June 4, 1993 BSD |
