==Synopsis==
<code lang="text">
#include "eif_cecil.h"
EIF_PROCEDURE eif_procedure (char * name, int * tid);
</code>
==Description==
The <code lang="text">eif_procedure</code> function returns the address of the Eiffel procedure of name <code lang="text">name</code> from the class, which type identifier is <code lang="text">tid</code>.
If the visible exception is enabled, it raises an visible exception upon failure.
==Return value==
Successful: Address of the procedure.
Failing: <code lang="text">NULL</code>. (The procedure does not exist or is not visible).
Otherwise, the address of the procedure is returned.
==Notes==
The Eiffel procedure cannot be a C external. In this case, you must directly call the C routine.
The return value is an address: to use it as a routine, you must call it with arguments or at least with ().
No argument type checking is done. You may cast the address of an Eiffel routine obtained with <code lang="text">eif_procedure</code> when calling it with real arguments.
==Conformance==
ISE Eiffel 4.4 and later.
==Compatibility==
<code lang="text">eif_procedure</code> is equivalent to <code lang="text">eif_proc</code>, which is deprecated.
