NAMEfclose - close a stream
DESCRIPTIONThe fclose() function flushes the stream pointed to by stream(writing any buffered output data using fflush(3)) and closes the underlying file descriptor.
RETURN VALUEUpon 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.
- The file descriptor underlying streamis not valid.
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).
CONFORMING TOPOSIX.1-2001, POSIX.1-2008, C89, C99.
NOTESNote 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).
