fclose

function

<cstdio>

int fclose ( FILE * stream );

Close file

Closes the file associated with the stream and disassociates it.
All internal buffers associated with the stream are flushed: the content of any unwritten buffer is written and the content of any unread buffer is discarded.
Even if the call fails, the stream passed as parameter will no longer be associated with the file.

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.
