# NAME
|
||
|
|
||
|
curl_escape - URL encodes the given string
|
||
|
|
||
|
# SYNOPSIS
|
||
|
|
||
|
~~~c
|
||
|
#include <curl/curl.h>
|
||
|
|
||
|
char *curl_escape(const char *string, int length);
|
||
|
~~~
|
||
|
|
||
|
# DESCRIPTION
|
||
|
|
||
|
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.
|
||
|
|
||

# EXAMPLE
|
||
|
|
||
|
~~~c
|
||
|
int main(void)
|
||
|
{
|
||
|
char *output = curl_escape("data to convert", 15);
|
||
|
if(output) {
|
||
|
printf("Encoded: %s\n", output);
|
||
|
curl_free(output);
|
||
|
}
|
||
|
}
|
||
|

|
||
|
|
||
|
# AVAILABILITY
|
||
|

|
||
|
