Implementation of All Exported Functions

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", &parameter) == FAILURE) { return; } RETURN_LONG(parameter); }

The function declaration is done using ZEND_FUNCTION, which corresponds to ZEND_FE in the function entry table (discussed earlier)_

After the declaration, code for checking and retrieving the function's arguments, argument conversion, and return value generation follows (more on this later)_
