NAME
       getnewbuf - General: Allocates a buf structure

SYNOPSIS
       struct buf * getnewbuf(
	       void );

ARGUMENTS

DESCRIPTION
       The  getnewbuf  routine	allocates a buf structure for performing I/O operations. This routine guarantees that the members of the structure
       are properly initialized prior to initiating the I/O request. Device drivers call this routine prior to calling

       physio, which performs the I/O operation.

RETURN VALUES
       Upon successful completion, getnewbuf returns a pointer to the allocated buf structure.	On failure, it returns a NULL pointer.
