Detailed Description

Fun VM opcode snippet: HTTP POST via libcurl (OP_CURL_POST).

This snippet is included by vm.c and implements the OP_CURL_POST instruction. When FUN_WITH_CURL is enabled, it performs an HTTP POST to the given URL with the provided request body and pushes the response body as a string. If libcurl support is not built in, or an error occurs, an empty string is pushed instead.

Stack behavior:

• Pops: body:string, url:string (values are converted via value_to_string_alloc)
• Pushes: body:string (server response; "" on error or when CURL is disabled)

Pops the POST body and URL, performs an HTTP POST, and pushes the response as a string. Without FUN_WITH_CURL, consumes two values and pushes an empty string.

Error handling:

• If URL conversion fails, the opcode pushes an empty string and discards any converted body.
• Follows redirects (CURLOPT_FOLLOWLOCATION = 1L).
• Sets CURLOPT_POST=1L and CURLOPT_POSTFIELDS to submit the body.

Notes:

• Uses FunCurlBuf and fun_curl_write_cb from the curl extension helpers.
• All temporary allocations (URL, body, response buffer) are freed.
