22 .TH curl_unescape 3 "22 March 2001" "libcurl 7.7" "libcurl Manual"
24 curl_unescape - URL decodes the given string
26 .B #include <curl/curl.h>
28 .BI "char *curl_unescape( char *" url ", int "length " );"
31 Obsolete function. Use \fIcurl_easy_unescape(3)\fP instead!
33 This function will convert the given URL encoded input string to a "plain
34 string" and return that as a new allocated string. All input characters that
35 are URL encoded (%XX where XX is a two-digit hexadecimal number) will be
36 converted to their plain text versions.
38 If the 'length' argument is set to 0, curl_unescape() will use strlen() on the
39 input 'url' string to find out the size.
41 You must curl_free() the returned string when you're done with it.
43 Since 7.15.4, \fIcurl_easy_unescape(3)\fP should be used. This function will
44 be removed in a future release.
46 A pointer to a zero terminated string or NULL if it failed.
