curl_escape(3) -- Linux man page

 

NAME

curl_escape - URL encodes the given string  

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

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.  

RETURN VALUE

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