NAME

       curl_easy_escape - URL encodes the given string

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
", output);
	   curl_free(output);
	 }
       }

NAME

       curl_easy_unescape - URL decodes the given string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_easy_unescape( CURL *curl, const char *url , int inlength, int *outlength );

DESCRIPTION

       This function converts the given URL encoded input string to a "plain string" and returns that in an allocated memory area. All input char-
       acters that are URL encoded (%XX where XX is a two-digit hexadecimal number) are converted to their binary versions.

       If the length argument is set to 0 (zero), curl_easy_unescape(3) will use strlen() on the input url string to find out the size.

       If outlength is non-NULL, the function will write the length of the returned string in the integer it points to.  This  allows  an  escaped
       string containing %00 to still get used properly after unescaping. Since this is a pointer to an int type, it can only return a value up to
       INT_MAX so no longer string can be unescaped if the string length is returned in this parameter.

       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_unescape(3) function.

RETURN VALUE

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