curl_free - reclaim memory that has been obtained through a libcurl call
SYNOPSIS
#include <curl/curl.h>
void curl_free( char *ptr );
DESCRIPTION
curl_free reclaims memory that has been obtained through a libcurl call. Use curl_free() instead of free() to avoid anomalies that can
result from differences in memory management between your application and libcurl.

curl_easy_escape(3) libcurl Manual curl_easy_escape(3)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);
}
}
