/**
|
|
* This module handles fetching of data from any url.
|
|
*
|
|
* Usage:
|
|
*
|
|
* fetch_init() must be called once before any other function. fetch_quit()
|
|
* must be called before exiting.
|
|
*
|
|
* fetch_start() will begin fetching a url. The function returns immediately.
|
|
* A pointer to an opaque struct fetch is returned, which can be passed to
|
|
* fetch_abort() to abort the fetch at any time. The caller must supply a
|
|
* callback function which is called when anything interesting happens. The
|
|
* callback function is first called with msg = FETCH_TYPE, with the
|
|
* Content-Type header in data, then one or more times with FETCH_DATA with
|
|
* some data for the url, and finally with FETCH_FINISHED. Alternatively,
|
|
* FETCH_ERROR indicates an error occurred: data contains an error message.
|
|
* FETCH_REDIRECT may replace the FETCH_TYPE, FETCH_DATA, FETCH_FINISHED
|
|
* sequence if the server sends a replacement URL.
|
|
* Some private data can be passed as the last parameter to fetch_start, and
|
|
* callbacks will contain this.
|
|
*
|
|
* fetch_poll() must be called regularly to make progress on fetches.
|
|
*
|
|
* fetch_filetype() is used internally to determine the mime type of local
|
|
* files. It is platform specific, and implemented elsewhere.
