I think that we need a function to get the size of a memory buffer (pdf-stm-buffer.h), something like, ## pdf_size_t pdf_stm_buffer_size (const pdf_stm_buffer_t buffer); ###
What do you think ?
Hm. It is true that the stm code is full of
buf->wp - buf->rp
to get the available data for read and of
buf->size - buf->wp
to get the available space for write.
Maybe we could define some macros. Would that be fine for you?
