curl_easy_unescape(3)                          libcurl Manual                          curl_easy_unescape(3)



NAME
       curl_easy_unescape - URL decodes the given string

SYNOPSIS
       #include <curl/curl.h>

       char *curl_easy_unescape( CURL *curl, char *url, int inlength , int *outlength );

DESCRIPTION
       This  function converts the given URL encoded input string to a "plain string" and returns that in an
       allocated memory area. All input characters that are URL encoded (%XX where XX is a  two-digit  hexa-decimal hexadecimal
       decimal number) are converted to their binary versions.

       If  the  length argument is set to 0 (zero), curl_easy_unescape(3) will use strlen() on the input url
       string to find out the size.

       If outlength is non-NULL, the function will write the length of the returned string in the integer it
       points  to. This allows an escaped string containing %00 to still get used properly after unescaping.

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

AVAILABILITY
       Added in 7.15.4 and replaces the old curl_unescape(3) function.

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