Function Documentation

_curl_tmpl_handle()

static int _curl_tmpl_handle ( void *  arg )

static

Free the curl easy handle.

Parameters

[in]

arg

curl easy handle to free.

fr_curl_easy_tls_init()

int fr_curl_easy_tls_init	(	fr_curl_io_request_t *	randle,
		fr_curl_tls_t const *	conf

Here is the call graph for this function:

fr_curl_init()

static int fr_curl_init ( void  )

static

Initialise global curl options.

libcurl is meant to performa reference counting, but still seems to leak lots of memory if we call curl_global_init many times.

Here is the call graph for this function:

fr_curl_response_certinfo()

int fr_curl_response_certinfo	(	request_t *	request,
		fr_curl_io_request_t *	randle
	)

Here is the caller graph for this function:

fr_curl_tmp_handle()

CURL* fr_curl_tmp_handle

(

void

)

Return a thread local curl easy handle.

This should only be used for calls into libcurl functions which don't operate on an active request, like the escape/unescape functions.

Returns

• A thread local curl easy handle.
• NULL on failure.
