NAME

fclose - close a stream  

SYNOPSIS

#include <stdio.h>

int fclose(FILE *stream); 

DESCRIPTION

The fclose() function flushes the stream pointed to by stream(writing any buffered output data using fflush(3)) and closes the underlying file descriptor.  

RETURN VALUE

Upon successful completion 0 is returned. Otherwise, EOFis returned and errnois set to indicate the error. In either case any further access (including another call to fclose()) to the stream results in undefined behavior.  

ERRORS

EBADF
The file descriptor underlying streamis not valid.

The fclose() function may also fail and set errnofor any of the errors specified for the routines close(2), write(2) or fflush(3).

CONFORMING TO

POSIX.1-2001, POSIX.1-2008, C89, C99.  

NOTES

Note that fclose() flushes only the user-space buffers provided by the C library. To ensure that the data is physically stored on disk the kernel buffers must be flushed too, for example, with sync(2) or fsync(2).
