22 .TH curl_unescape 3 "February 03, 2016" "libcurl 7.59.0" "libcurl Manual"
25 curl_unescape - URL decodes the given string
27 .B #include <curl/curl.h>
29 .BI "char *curl_unescape( const char *" url ", int "length " );"
32 Obsolete function. Use \fIcurl_easy_unescape(3)\fP instead!
34 This function will convert the given URL encoded input string to a "plain
35 string" and return that as a new allocated string. All input characters that
36 are URL encoded (%XX where XX is a two-digit hexadecimal number) will be
37 converted to their plain text versions.
39 If the 'length' argument is set to 0, curl_unescape() will use strlen() on the
40 input 'url' string to find out the size.
42 You must \fIcurl_free(3)\fP the returned string when you're done with it.
44 Since 7.15.4, \fIcurl_easy_unescape(3)\fP should be used. This function will
45 be removed in a future release.
47 A pointer to a zero terminated string or NULL if it failed.
