- .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 fBlengthfP argument is set to 0 (zero), fIcurl_easy_unescape(3)fP
- will use strlen() on the input fIurlfP string to find out the size.
- If fBoutlengthfP 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.
- .SH "SEE ALSO"
- .I curl_easy_escape(3), curl_free(3), RFC 2396
