| .TH curl_easy_unescape 3 "7 April 2006" "libcurl 7.15.4" "libcurl Manual" |
| .SH NAME |
| curl_easy_unescape - URL decodes the given string |
| .SH SYNOPSIS |
| .B #include <curl/curl.h> |
| .sp |
| .BI "char *curl_easy_unescape( CURL *" curl ", char *" url ", int "inlength |
| .BI ", int *" outlength " );" |
| .ad |
| .SH 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 hexadecimal number) are converted to |
| their binary versions. |
| |
| If the \fBlength\fP argument is set to 0 (zero), \fIcurl_easy_unescape(3)\fP |
| will use strlen() on the input \fIurl\fP string to find out the size. |
| |
| If \fBoutlength\fP 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 \fIcurl_free(3)\fP the returned string when you're done with it. |
| .SH AVAILABILITY |
| Added in 7.15.4 and replaces the old \fIcurl_unescape(3)\fP function. |
| .SH RETURN VALUE |
| A pointer to a zero terminated string or NULL if it failed. |
