Thanks Vadim! Is there a way, in windows, to determine if data is
ready for reading in from a terminal interface? The FIONREAD ioctl
works on linux, and there is the following non-blocking generic code
which appears in force on windows:
#ifdef LISTEN_USE_FCNTL
do { int c = 0;
FILE *fp = strm->sm.sm_fp;
int orig;
int res;
if (feof(fp)) return TRUE;
orig = fcntl(fileno(fp), F_GETFL);
if (! (orig & O_NONBLOCK ) ) {
res=fcntl(fileno(fp),F_SETFL,orig | O_NONBLOCK);
}
c = getc(fp);
if (! (orig & O_NONBLOCK ) ){
fcntl(fileno(fp),F_SETFL,orig );
}
if (c != EOF)
{
ungetc(c,fp);
return TRUE;
}
return FALSE;
} while (0);
#endif
that is, presuming the configure check
check for listen using fcntl
returns yes. Can you tell me if the latter is true or not, and then
if so, what are the symptoms of breakage in light of the code above?
Unfortunately LISTEN_USE_FCNTL is not set on Windows MinGW.
