Flush all input/output buffers
#include <stdio.h> int flushall( void );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The flushall() function flushes all buffers associated with open input/output streams. A subsequent read operation on an input stream reads new data from the associated stream.
Calling the flushall() function is equivalent to calling fflush() for all open streams.
- An error occurred (errno is set).
The QNX 4 version of this function returns the number of streams flushed.
