curl_escape - Man Page
URL encodes the given string
Synopsis
#include <curl/curl.h> char *curl_escape(const char *url, int length);
Description
Obsolete function. Use curl_easy_escape(3) instead!
This function will convert 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 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(3) will use strlen() on the input url string to find out the size.
You must curl_free(3) the returned string when you are done with it.
Example
char *output = curl_escape("data to convert", 15); if(output) { printf("Encoded: %s\n", output); curl_free(output); }
Availability
Since 7.15.4, curl_easy_escape(3) should be used. This function will be removed in a future release.
Return Value
A pointer to a null-terminated string or NULL if it failed.
