The following simple program:

	#include <stdio.h>
	main() {
		FILE *pipe;
		int code;

		pipe = popen("/usr/bin/false", "w");
		code = pclose(pipe);
		printf("/usr/bin/false's result was %d\n", code);

		pipe = popen("/usr/bin/true", "w");
		code = pclose(pipe);
		printf("/usr/bin/true's result was %d\n", code);
	}

Produces:
	/usr/bin/false's result was 256
	/usr/bin/true's result was 0

I checked and rechecked -- false(1) returns 1

	mi@guest:/tmp (1099) false
	mi@guest:/tmp (1100) echo $status
	1

According to pclose(3), its result must be the exit code of the process.
Is this a bug, or do I misunderstand the manual? Thanks!

	-mi
