Well. It seems my former message was unclear?<br><br>Here is a more precise question: should/could C allocated bigarrays<br>&nbsp;be freed?<br><br>Context:<br><br>OCaml calls one C function M, at about 50 Hz.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;  
<br>In M,&nbsp; a C function (let&#39;s call it A) is locally defined.<br>One pointer to A is given to another function, that<br>calls A more than once.<br><br>Function A wraps a C array it receives as a parameter<br>into a bigarray, and give it to OCaml through one callback.
<br><br>The whole process is repeated, at about 50 Hz.<br><br>I do not know if the bigarrays allocated by M are garbage<br>collected in any way, and if they are not, how I could free<br>them in order to avoid any memory leak?
<br><br>Thanks in advance<br>Salutations<br><br>Matthieu<br>
