◆ httpHeaderParseOffset()

bool httpHeaderParseOffset ( const char *  start,
int64_t *  offPtr,
char **  endPtr = nullptr 

A strtoll(10) wrapper that checks for strtoll() failures and other problems. XXX: This function is not fully compatible with some HTTP syntax rules. Just like strtoll(), allows whitespace prefix, a sign, and any suffix. Requires at least one digit to be present. Sets "off" and "end" arguments if and only if no problems were found.

◆ httpHeaderParseQuotedString()

int httpHeaderParseQuotedString ( const char *  start,
const int  len,
String val 

Parses a quoted-string field (RFC 2616 section 2.2), complains if something went wrong, returns non-zero on success. Un-escapes quoted-pair characters found within the string. start should point at the first double-quote.
