curl_escape3
Url encode a string
Usage
#include <curl/curl.h> char *curl_escape(const char *string, int length);
Overview
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). Although not constrained by its type, the returned string may not be altered.
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.
