Manual Section... (3) - page: fclose
NAMEfclose - close a stream
DESCRIPTIONThe fclose() function will flushes the stream pointed to by fp (writing any buffered output data using fflush(3)) and closes the underlying file descriptor.
RETURN VALUEUpon successful completion 0 is returned. Otherwise, EOF is returned and errno is 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 fp is not valid.
CONFORMING TOC89, C99.
NOTESNote that fclose() only flushes 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).
