Error handling: how to get specific error messages?

[wonter]

I found the basic error handling in README:

if (parser->upgrade) {
  /* handle new protocol */
} else if (nparsed != recved) {
  /* Handle error. Usually just close the connection. */
}

But how can I get more specific error messages?

Something like invalid HTTP method error message.

try:

const char *err_name = http_errno_name(HTTP_PARSER_ERRNO(parser));
const char *err_desc = http_errno_description(HTTP_PARSER_ERRNO(parser));

try:

const char *err_name = http_errno_name(HTTP_PARSER_ERRNO(parser));
const char *err_desc = http_errno_description(HTTP_PARSER_ERRNO(parser));

Sorry, I have another question.

Is HTTP_PARSER_ERRNO(parser) always be set when an error occurred??

I mean, will HTTP_PARSER_ERRNO(parser) be set when nparsed != recved?

[ploxiln]

yes

to be sure you can check if (HTTP_PARSER_ERRNO(parser) != 0)
