.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. | |
