It would be probably good idea to also remove tools/docgen.py and asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which may contain some useful info which we'll need at least to review before removing. PUBLISHED_FROM=faf454d4c52a2f07ea8ac084cf0bd11a0c9c9b3b

Parse HTTP header `hdr`. Find variable `var_name` and store it's value
|
|
in the buffer `buf`, `buf_size`. Return 0 if variable not found, non-zero
|
|
otherwise.
|
|
|
|
This function is supposed to parse
|
|
cookies, authentication headers, etcetera. Example (error handling omitted):
|
|
|
|
char user[20];
|
|
struct mg_str *hdr = mg_get_http_header(hm, "Authorization");
|
|
mg_http_parse_header(hdr, "username", user, sizeof(user));
|
|
|
|
Return length of the variable's value. If buffer is not large enough,
|
|
or variable not found, 0 is returned.
