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).
