function
<cstdio>

fclose

int fclose ( FILE * stream );
Close file
Closes the file associated with the stream and disassociates it.

All internal buffers associated with the stream are disassociated from it and flushed: the content of any unwritten output buffer is written and the content of any unread input buffer is discarded.

Even if the call fails, the stream passed as parameter will no longer be associated with the file nor its buffers.

Parameters

stream
Pointer to a FILE object that specifies the stream to be closed.

Return Value

If the stream is successfully closed, a zero value is returned.
On failure, EOF is returned.

/* fclose example */
#include <stdio.h>
int main ()
{
  FILE * pFile;
  pFile = fopen ("myfile.txt","wt");
  fprintf (pFile, "fclose example");
  fclose (pFile);
  return 0;
}

This simple code creates a new text file, then writes a sentence to it, and then closes it.
