curl_escape(3)

NAME
curl_escape - URL encode a string

SYNOPSIS
#include <curl/curl.h>
char *curl_escape(const char *string, int length);

DESCRIPTION
Obsolete function. Use curl_easy_escape(3) instead! This function converts 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 are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number). If the length argument is set to 0, curl_escape(3) uses strlen() on string to find out the size. You must curl_free(3) the returned string when you are done with it.

PROTOCOLS
This functionality affects all supported protocols

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

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

RETURN VALUE
