.TH curl_unescape 3 "22 March 2001" "libcurl 7.7" "libcurl Manual"
.SH NAME
curl_unescape - URL decodes the given string
.SH SYNOPSIS
.nf
#include <curl/curl.h>
char *curl_unescape( const char *url, int length);
.fi
.SH DESCRIPTION
Obsolete function. Use \fIcurl_easy_unescape(3)\fP instead!
This function will convert the given URL encoded input string to a "plain
string" and return that as a new allocated string. All input characters that
are URL encoded (%XX where XX is a two-digit hexadecimal number) will be
converted to their plain text versions.
If the 'length' argument is set to 0, curl_unescape() will use strlen() on the
input 'url' string to find out the size.
You must \fIcurl_free(3)\fP the returned string when you are done with it.
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
int decodelen;
char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
if(decoded) {
/* do not assume printf() works on the decoded data! */
printf("Decoded: ");
/* ... */
curl_free(decoded);
}
}
.fi
.SH AVAILABILITY
Since 7.15.4, \fIcurl_easy_unescape(3)\fP should be used. This function will
be removed in a future release.
.SH RETURN VALUE
A pointer to a null-terminated string or NULL if it failed.
