native callfunc_push_str(const VALUE, bool:copyback = true);
String to push
If true, any changes made in the called function will be
copied back to the calling plugin
Pushes a string onto the current call.
This will defy the "const" specifier if copyback is true, which is
only kept for special backwards compatibility.
This function has no return value.
If called without initiating a callfunc, or the maximum
amount of parameters is reached, an error is thrown.
