3.1.36.perprintf() #
NAME
perprintf — enable automatic stream flushing
noperprintf – reset (disable) automatic stream flushing
SYNOPSIS
#include <stdio.h>
- void perprintf(FILE * stream);
- void noperprintf(FILE * stream)
DESCRIPTION
To flush the output immediately after executing a printf(), use perprintf(). This command sets the file stream to automatically flush the output after every write request on the selected stream.
To stop automatic output flushes, use noperprintf().
RETURN VALUES
None
ERRORS
No errors are defined.
EXAMPLE
void Init_function ()
{
//stdout init
perprintf(stdout_init(“/dev/ttyS1”));
//stdin init
stdin_init (“/dev/ttyS1”);
}
