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 charac-
       ters that are URL encoded (%XX where XX is a two-digit hexadecimal num-
       ber) are converted to their binary versions.

       If  the  length  argument is set to 0 (zero), curl_easy_unescape() 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() function.

RETURN VALUE

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