how to use md_parse() ?

string text="xxxxxxxxxxxx";
md_parse(text.c_str(),text.length(),NULL,NULL);

[1] 7099 segmentation fault (core dumped)

I can't understand when reading md4c.h.

What is the function of void* userdata？

Can you give me a use case？

Thank you so much.

See e.g. the markdown to HTML convertor: https://github.com/mity/md4c/blob/master/src/md4c-html.c#L571

userdata is a pointer to any your data, you want to pass to the callbacks. You have to provide pointer to a structure in the 3rd param, which provides function pointers to your callbacks processing the parsed data.

Thank you very much! I solve the problem successfully. md4c runs very fast.
