fclose()

This is a File I/O function. It is not implemented in the Compiler.

#include <stdio.h>

  

  int fclose(FILE *f);

  

fclose() closes file f. Before doing so, it does the following:

• flushes the stream, if the file was not opened in read-only mode
• discards and deallocates any buffers that were allocated automatically, i.e., not using setbuf().

Zero, if the function succeeds; EOF otherwise.
