curl_escape(3)

NAME

curl_escape - URL encodes the given string

SYNOPSIS

#include <curl/curl.h>

char *curl_escape(const char *url, int length);

DESCRIPTION

Obsolete function. Use curl_easy_escape(3) instead!

This function will convert the given input string to an 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 (%NN where NN is a two-digit hexadecimal number).

If the lengthf argument is set to 0, curl_escape() will use strlen() on the input url string to find out the size.

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

EXAMPLE

char *output = curl_escape("data to convert", 15);
if(output) {
printf("Encoded: %s\n", output);
curl_free(output);
}

AVAILABILITY

Since 7.15.4, curl_easy_escape(3) should be used. This function will be removed in a future release.

RETURN VALUE

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