--TEST--
|
|
proc_open with only one argv
|
|
--DESCRIPTION--
|
|
This test tries out a very esoteric functionality: Passing no argv[0] to a
|
|
program. There's absolutely no reason anyone would do this in practice, but the
|
|
entire point of the bypass_shell patch was to allow 100% control over the child
|
|
process, so the option is there. Keep in mind that actually using this
|
|
"feature" will probably crash most programs one could run, since the expression
|
|
argc > 0 in a main() function is pretty much guaranteed by POSIX. It's
|
|
interesting to note that PHP itself handles this case gracefully.
