curl_unescape(3) URL decodes the given string


#include <curl/curl.h>

char *curl_unescape( const char *url, int length );


Obsolete function. Use curl_easy_unescape(3) instead!

This function will convert the given URL encoded input string to a "plain string" and return that as a new allocated string. All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal number) will be converted to their plain text versions.

If the 'length' argument is set to 0, curl_unescape() will use strlen() on the input 'url' string to find out the size.

You must curl_free(3) the returned string when you're done with it.


Since 7.15.4, curl_easy_unescape(3) should be used. This function will be removed in a future release.


A pointer to a zero terminated string or NULL if it failed.
