24 .TH curl_easy_unescape 3 "7 April 2006" "libcurl 7.15.4" "libcurl Manual"
\r
26 curl_easy_unescape - URL decodes the given string
\r
28 .B #include <curl/curl.h>
\r
30 .BI "char *curl_easy_unescape( CURL *" curl ", char *" url ", int "inlength
\r
31 .BI ", int *" outlength " );"
\r
34 This function converts the given URL encoded input string to a "plain string"
\r
35 and returns that in an allocated memory area. All input characters that are
\r
36 URL encoded (%XX where XX is a two-digit hexadecimal number) are converted to
\r
37 their binary versions.
\r
39 If the \fBlength\fP argument is set to 0 (zero), \fIcurl_easy_unescape(3)\fP
\r
40 will use strlen() on the input \fIurl\fP string to find out the size.
\r
42 If \fBoutlength\fP is non-NULL, the function will write the length of the
\r
43 returned string in the integer it points to. This allows an escaped string
\r
44 containing %00 to still get used properly after unescaping.
\r
46 You must \fIcurl_free(3)\fP the returned string when you're done with it.
\r
48 Added in 7.15.4 and replaces the old \fIcurl_unescape(3)\fP function.
\r
50 A pointer to a zero terminated string or NULL if it failed.
