<title>Calling Function Pointers</title>

<para>

For clarity, it is preferred to explicitly dereference a function pointer

when calling the pointed-to function if the pointer is a simple variable,

for example:

<programlisting>

(*emit_log_hook) (edata);

</programlisting>

(even though <literal>emit_log_hook(edata)</literal> would also work).

When the function pointer is part of a structure, then the extra

punctuation can and usually should be omitted, for example:

<programlisting>

paramInfo->paramFetch(paramInfo, paramId);

</programlisting>
