.SH DESCRIPTION
|
|
|
|
|
This function will convert the given input string to an URL encoded string and
|
|
|
|
|
return that as a new allocated string. All input characters that are not a-z,
|
2001-03-22 15:06:31 -05:00
|
|
|
A-Z or 0-9 will be converted to their "URL escaped" version. If a sequence of
|
|
|
|
|
%NN (where NN is a two-digit hexadecimal number) is found in the string to
|
|
|
|
|
encode, that 3-letter combination will be copied to the output unmodifed,
|
|
|
|
|
assuming that it is an already encoded piece of data.

|
|
|
|
|
|
|
|
If the 'length' argument is set to 0, curl_escape() will use strlen() on the
|
|
|
|
|
input 'url' string to find out the size.
|
|
|
|
|
|
|
|
|
|
You must free() the returned string when you're done with it.
|
|
|
|
|
.SH RETURN VALUE
|
|
|
|
|
A pointer to a zero terminated string or NULL if it failed.
