.TH curl_escape 3 "January 02, 2023" "libcurl 7.88.1" "libcurl Manual"
.SH NAME
curl_escape - URL encodes the given string
.SH SYNOPSIS
.nf
#include <curl/curl.h>
char *curl_escape(const char *url, int length);
.fi
.SH DESCRIPTION
Obsolete function. Use \fIcurl_easy_escape(3)\fP instead!
This function will convert the given input string to a URL encoded string and
return that as a new allocated string. All input characters that are not a-z,
A-Z or 0-9 will be converted to their "URL escaped" version (\fB%NN\fP where
\fBNN\fP is a two-digit hexadecimal number).
If the \fBlength\fP argument is set to 0, \fIcurl_escape(3)\fP will use
strlen() on the input \fBurl\fP string to find out the size.
You must \fIcurl_free(3)\fP the returned string when you are done with it.
.SH EXAMPLE
.nf
char *output = curl_escape("data to convert", 15);
if(output) {
printf("Encoded: %s\\n", output);
curl_free(output);
}
.fi
.SH AVAILABILITY
Since 7.15.4, \fIcurl_easy_escape(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.
