Linux / Unix Command: fclose

Command Library

NAME

fclose - close a stream  

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 VALUE

Upon successful completion 0 is returned. Otherwise, EOF is returned and the global variable errno is set to indicate the error. In either case any further access (including another call to fclose()) to the stream results in undefined behaviour.  

ERRORS

EBADF

The filedescriptor underlying stream is not valid.

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

SEE ALSO

close(2), fcloseall(3), fflush(3), fopen(3), setbuf(3)
