Detailed Description

libcurl helpers and buffers used by HTTP-related VM opcodes.

Declares small buffer helpers and libcurl write callbacks that support network-related opcodes when FUN_WITH_CURL is enabled.

Function Documentation

fun_curl_file_write_cb()

size_t fun_curl_file_write_cb ( void * ptr, size_t sz, size_t nm, void * ud )

static

libcurl write callback that writes directly to a FILE*.

Parameters

ptr	Pointer to incoming data.
sz	Size of each element.
nm	Number of elements.
ud	User data; must be a FILE* opened for writing in binary mode.

Returns

Number of elements written (as returned by fwrite).

fun_curl_write_cb()

size_t fun_curl_write_cb ( void * ptr, size_t sz, size_t nm, void * ud )

static

libcurl write callback that appends data to a FunCurlBuf.

Reallocates the destination buffer as needed and keeps it NUL-terminated.

Parameters

ptr	Pointer to incoming data block provided by libcurl.
sz	Size of each data element.
nm	Number of elements in this block.
ud	User data; must be a FunCurlBuf*.

Returns

Number of bytes actually handled (sz*nm) on success, 0 on failure to signal an error to libcurl.
