Re: why is this not a bug?

Hmm... on my bsd system... philip@illiad:~/tmp% cat foo.c #include <stdio.h> void main() { FILE *fd; fd = popen("/usr/turkey", "w"); if( fd ) { printf("popen succeeded\n"); }else { printf("popen failed\n"); } } philip@illiad:~/tmp% ./a.out popen succeeded philip@illiad:~/tmp% /usr/turkey: not found philip@illiad:~/tmp% ??? Isn't popen supposed to return NULL? This would appear that it's copmletely outside of PHP, but still... am I missing something?
