<p>Comment (by Roland Haas):</p>
<p>Might be good to have a test case that checks that the return value of the Fortran function returns the same value as the C function would and that the expected pointer shows up in the function’s argument list. To make sure the Fortran compiler still passes just a plain pointer and not something else.</p>
<p>It should since the <code>type(*)</code> construct seems to be explicitly designed to handle C functions that take <code>void*</code> as argument. <a data-is-external-link="true" href="https://www.ibm.com/support/knowledgecenter/SSAT4T_15.1.4/com.ibm.xlf1514.lelinux.doc/language_ref/assumedtypeobj.html" rel="nofollow">https://www.ibm.com/support/knowledgecenter/SSAT4T_15.1.4/com.ibm.xlf1514.lelinux.doc/language_ref/assumedtypeobj.html</a> says:</p>
<blockquote>
<p>To facilitate the interoperability with formal parameters of type void* in C procedures, assumed-type arguments are introduced in Fortran. Assumed-type arguments are entities that are declared with the TYPE(*) specifier.</p>
