fclose(3) |

fclose − close a stream
#include <stdio.h>
int fclose(FILE *fp);
The fclose() function will flush the stream pointed to by fp (writing any buffered output data using fflush(3)) and close the underlying file descriptor.
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.

The file descriptor underlying fp 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).
Note 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, e.g. with sync(2) or fsync(2).
