curl_unescape(3) libcurl Manual curl_unescape(3) NAME curl_unescape - URL decodes the given string SYNOPSIS #include <curl/curl.h> char *curl_unescape( const 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(3) the returned string when you are done with it. EXAMPLE CURL *curl = curl_easy_init(); if(curl) { int decodelen; char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen); if(decoded) { /* do not assume printf() works on the decoded data! */ printf("Decoded: "); /* ... */ curl_free(decoded); } } 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 null-terminated string or NULL if it failed.
