7 curl_unescape - URL decodes the given string
9 .B #include <curl/curl.h>
11 .BI "char *curl_unescape( char *" url ", int "length " );"
14 This function will convert the given URL encoded input string to a "plain
15 string" and return that as a new allocated string. All input characters that
16 are URL encoded (%XX where XX is a two-digit hexadecimal number, or +) will be
17 converted to their plain text versions (up to a ? letter, no + letters to the
18 right of a ? letter will be converted).
20 If the 'length' argument is set to 0, curl_unescape() will use strlen() on the
21 input 'url' string to find out the size.
23 You must curl_free() the returned string when you're done with it.
25 A pointer to a zero terminated string or NULL if it failed.
