pmhttpNewClient allocates and initializes an opaque HTTP client
that is ready to make requests from a server.
The URL request interface pmhttpClientFetch issues an HTTP GET
request to the server specified in the supplied url. The body of
the response is returned in the caller supplied bodybuf buffer,
of bodylen bytes length. An optional typebuf buffer, of typelen
bytes length, can also be supplied and (if non-NULL) will contain
the value of the content-type header returned from the server.
The url parameter is an RFC1630 format URL. This will typically
be prefixed with "http://", however these interfaces also support
Unix domain sockets. Those are instead prefixed by "unix://",
followed by the full filesystem path to the desired Unix domain
To free up resources associated with an HTTP client, including
closing any persistent server connection that has been
established earlier, is accomplished using the pmhttpFreeClient
pmhttpNewClient will return NULL on failure, which can only occur
when allocation of memory is not possible.
pmhttpClientFetch will return the number of bytes places into the
bodybuf buffer, else a negated error code indicating the nature
of the failure.
