This URL parser was extracted from http-parser, which is no longer actively maitained. It was previouly used by NodeJS.
It is a simplistic zero-copy URL parser designed for performance. It does not make any syscalls nor allocations. It can be interrupted at anytime. It has no dependencies.
/* Initialize all http_parser_url members to 0 */
void http_parser_url_init(struct http_parser_url *u);
/* Parse a URL; return nonzero on failure */
int http_parser_parse_url(const char *buf, size_t buflen,
int is_connect,
struct http_parser_url *u);See url_parser.h for details.
There is a demo program included. Build it with make url_parser.
Run the tests with make test.
