Implementing the exported functions is the final step. The example function in first_module looks like this:
ZEND_FUNCTION(first_module) { long parameter; if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "l", ¶meter) == FAILURE) { return; } RETURN_LONG(parameter); } |
After the declaration, code for checking and retrieving the function's arguments, argument conversion, and return value generation follows (more on this later).
