curl_escape(3) URL encodes the given string


#include <curl/curl.h>

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


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 'length' 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're done with it.


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


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