curl_unescape(3) libcurl Manual curl_unescape(3)

NAME curl_unescape - URL decodes the given string

SYNOPSIS #include <curl/curl.h>

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

DESCRIPTION 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 hexadeci- mal 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() the returned string when youre done with it.

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

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