Since you are working with integers, you can do:
zend_long prevcount = 0;
if(zend_parse_parameters(ZEND_NUM_ARGS(), "|l", &prevcount) == FAILURE)
{
return;
}
if(prevcount)
{
/* ... use prevcount ... */
}
Notice that all integers returned from the ZPP is a zend_long, you can
see more information about the ZPP in
php-src/README.PARAMETER_PARSING_API
