There may possibly be something wrong with fl_exe_command() (though I
don't think so), but there is definitely something wrong with the way
I read manual pages. (Gotta get my eyes tested!)
The workaround should be
#include <sys/types.h>
#include <sys/wait.h>
#define NONBLOCK 0
#define BLOCK 1
long pid;
FL_OBJECT *status;
pid=fl_exe_command("mcopy -n a:file", NONBLOCK);
for (;;) {
int cmd_status;
fl_addto_browser_chars(status,".");
if ( waitpid( pid, &cmd_status, WNOHANG ) == pid ) {
fl_end_command(pid);
break;
}
sleep(1);
}
You may want to check the manual page for waitpid(2) just to be sure
that I haven't screwed up somewhere else. Again, you may wish to
check the value of `cmd_status' upon completion. Refer to the manual
page for instructions on how to parse it.
This will teach me to try to whip out answers while on the telephone.
