|
.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 ", const char *" url
|
|
.BI ", int "inlength ", 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. Since this is a
|
|
pointer to an \fIint\fP type, it can only return a value up to INT_MAX so no
|
|
longer string can be unescaped if the string length is returned in this
|
|
parameter.
|
|
|
|
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 null-terminated string or NULL if it failed.
