[9fans] pwd(1)

[9fans] pwd(1)

[lucio]

Does it really return the value of the pathname which it failed to
retrieve when it fails to retrieve it?

	if(getwd(pathname, sizeof(pathname)) == 0) {
		print("pwd: %r\n");
		exits(pathname);
	}

I hope I'm looking at old code.  Did somebody forget to put quotes
around the exits() argument?

You're looking at half-old code.  The truly old code says:

g% cat /n/bootes/sys/src/cmd/pwd.c
 #include <u.h>
 #include <libc.h>
/*
 * Print working (current) directory
 */

void
main(int argc, char *argv[])
{
	char pathname[512];

	USED(argc, argv);
	if(getwd(pathname, sizeof(pathname)) == 0) {
		print("pwd: %s\n", pathname);
		exits(pathname);
	}
	print("%s\n", pathname);
	exits(0);
}
g%

which is the way getwd worked before 9P2000.
I changed the current pwd just to exits("getwd")
when getwd fails (after printing %r).

Would it be silly to ask for the error message to be output to stderr
rather than stdout?
