curl_escape - URL encodes the given string
#include <curl/curl.h>
char *curl_escape(const char *string, int length);
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).
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.
int main(void)
{
char *output = curl_escape("data to convert", 15);
if(output) {
printf("Encoded: %s\n", output);
curl_free(output);
}
}
Since 7.15.4, curl_easy_escape(3) should be used. This function might be removed in a future release.
A pointer to a null-terminated string or NULL if it failed.
