This is a rewrite of the patch from Soapyman here https://github.com/warmcat/libwebsockets/pull/363 The main changes compared to Soapyman's original patch are - There's no new stuff in the info struct user code does any overrides it may want to do explicitly after lws_context_create returns - User overrides for file ops can call through (subclass) to the original platform implementation using lws_get_fops_plat() - A typedef is provided for plat-specific fd type - Public helpers are provided to allow user code to be platform-independent about file access, using the lws platform file operations underneath: static inline lws_filefd_type lws_plat_file_open(struct lws_plat_file_ops *fops, const char *filename, unsigned long *filelen, int flags) static inline int lws_plat_file_close(struct lws_plat_file_ops *fops, lws_filefd_type fd) static inline unsigned long lws_plat_file_seek_cur(struct lws_plat_file_ops *fops, lws_filefd_type fd, long offset_from_cur_pos) static inline int lws_plat_file_read(struct lws_plat_file_ops *fops, lws_filefd_type fd, unsigned long *amount, unsigned char *buf, unsigned long len) static inline int lws_plat_file_write(struct lws_plat_file_ops *fops, lws_filefd_type fd, unsigned long *amount, unsigned char *buf, unsigned long len) There's example documentation and implementation in the test server.
