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 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 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.
