NAME
GetDeviceProc -- Finds a handler to send a message to (V36)
SYNOPSIS
devproc = GetDeviceProc(name, devproc)
D0 D1 D2
struct DevProc *GetDeviceProc(STRPTR, struct DevProc *)FUNCTION
Finds the handler/filesystem to send packets regarding 'name' to. This may involve getting temporary locks. It returns a structure that includes a lock and msgport to send to to attempt your operation. It also includes information on how to handle multiple-directory assigns (by passing the DevProc back to GetDeviceProc() until it returns NULL).
The initial call to GetDeviceProc() should pass NULL for devproc. If after using the returned DevProc, you get an ERROR_OBJECT_NOT_FOUND, and (devproc->dvp_Flags & DVPF_ASSIGN) is true, you should call GetDeviceProc() again, passing it the devproc structure. It will either return a modified devproc structure, or NULL (with ERROR_NO_MORE_ENTRIES in IoErr()). Continue until it returns NULL.
This call also increments the counter that locks a handler/fs into memory. After calling FreeDeviceProc, do not use the port or lock again!
INPUTS
name - name of the object you wish to access. This can be a relative path ("foo/bar"), relative to the current volume (":foo/bar"), or relative to a device/volume/assign ("foo:bar"). devproc - A value returned by GetDeviceProc() before, or NULL
RESULT devproc - a pointer to a DevProc structure or NULL
BUGS Counter not currently active in 2.0. In 2.0 and 2.01, you HAD to check DVPF_ASSIGN before calling it again. This was fixed for the 2.02 release of V36.
