curl_escape - URL encode the given string

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 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 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 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.
