Due to my pretty rusty C skills I have what I hope is a naive question. I'm writing a cffi interface to the tidy lib which among other things has the following construct:
// in include file: struct _TidyBuffer; typedef struct _TidyBuffer TidyBuffer; typedef void* TidyDoc;
// example caller: TidyBuffer output = {0}; TidyDoc tdoc = tidyCreate(); ... tidySaveBuffer(tdoc, &output) ...
so, tidy allocates some memory from a pointer reference supplied by the client. How do I declare and pass this reference to the foreign function?
