## NAME

curl_easy_escape - URL encodes the given string

## SYNOPSIS

#include <curl/curl.h>

char *curl_easy_escape( CURL * curl , char * url , int length );

## DESCRIPTION

This function converts the given input string to an URL encoded string and returns that as a new allocated string. All input characters that are not a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number).

If the length argument is set to 0 (zero), curl_easy_escape(3) uses strlen() on the input url to find out the size.

You must curl_free(3) the returned string when you're done with it.

## AVAILABILITY

Added in 7.15.4 and replaces the old curl_escape(3) function.

## RETURN VALUE

A pointer to a zero terminated string or NULL if it failed.
