fflush − flush a stream
#include <stdio.h>
int fflush(FILE *stream);
The function fflush forces a write of all buffered data for the given output or update stream via the stream’s underlying write function. The open status of the stream is unaffected.
If the stream argument is NULL, fflush flushes all open output streams.
Upon successful completion 0 is returned. Otherwise, EOF is returned and the global variable errno is set to indicate the error.
