fclose, fflush - close or flush a stream SYNOPSIS
#include <stdio.h> int fclose(FILE *stream) int fflush(FILE *stream) DESCRIPTION
Fclose causes any buffers for the named stream to be emptied, and the file to be closed. Buffers allocated by the standard input/output system are freed. Fclose is performed automatically upon calling exit(3). Fflush causes any buffered data for the named output stream to be written to that file. The stream remains open. SEE ALSO
close(2), fopen(3), setbuf(3). DIAGNOSTICS
These routines return EOF if stream is not associated with an output file, or if buffered data cannot be transferred to that file. 7th Edition May 15, 1985 FCLOSE(3)

fclose, fcloseall -- close a stream LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdio.h> int fclose(FILE *stream); void fcloseall(void); 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). The fcloseall() function calls fclose() on all open streams. 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''). The fcloseall() function first appeared in FreeBSD 7.0. BSD
