Function Documentation

char* rfc1738_do_escape ( const char *  url,
int  flags 
)

RFC 1738 URL-escaping

Public API is formed of a triplet of encode functions mapping to the rfc1738_do_encode() engine.

ASCII characters are split into four groups:

  • SAFE Characters which are safe to occur in any URL. For example A,B,C
  • CTRLS Binary control codes. Dangerous to include in URLs.
  • UNSAFE Characters which are completely usafe to occur in any URL. For example; backspace, tab, space, newline.
  • RESERVED Characters which are reserved for special meaning and may only occur in certain parts of a URL.

Returns a static buffer containing the RFC 1738 compliant, escaped version of the given url.

Parameters
flagsRFC1738_ESCAPE_CTRLS Encode the blatantly dangerous binary codes.
flagsRFC1738_ESCAPE_UNSAFE Encode printable unsafe characters (excluding CTRLs).
flagsRFC1738_ESCAPE_RESERVED Encode reserved characters.
flagsRFC1738_ESCAPE_ALL Encode all binary CTRL, unsafe and reserved characters.
flagsRFC1738_ESCAPE_NOSPACE Ignore the space whitespace character.
flagsRFC1738_ESCAPE_NOPERCENT Ignore the escaping delimiter ''.
