Hi,
I have an internal function defined that returns an array zval:
zval *pow_zstring_internal_split(Z_STRVAL_P(ivalue), separator, count, 0
TSRMLS_DC);
When I call it like this, return_value is NULL in userland.
return_value = pow_zstring_internal_split(Z_STRVAL_P(ivalue), separator,
count, 0 TSRMLS_CC);
But when I call it like this, it works as expected and an array is returned
to userland
array = pow_zstring_internal_split(Z_STRVAL_P(ivalue), separator, count, 0
TSRMLS_CC);
*return_value = *array;
I'm sure there is an obvious answer, but given my background (or lack
thereof) in C, I can't figure it out.
How does the temporary assignment change things inside the engine?
Bob
