SYNOPSIS

#include <curl/curl.h>

char *curl_easy_escape( CURL *curl, const char *string , int length );

DESCRIPTION

This function converts the given input string to a 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 length is set to 0 (zero), curl_easy_escape(3) uses strlen() on the input string 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.

EXAMPLE

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