# File: d3dxerr.w
# Purpose: Generates d3dxerr.h and d3dxerrswitch.h
# Includes: d3dxerrdef.w
#
# Description: d3dxerr.h is an external D3DX header containing D3DXERR_*
# definitions. d3dxerrswitch.h contains the guts of a C switch
# statement that assigns strings to an LPSTR based on a given
# D3DXERR_. The switch statement which #includes d3dxerrswitch.h
# is in the implementation of D3DXGetErrorString in d3dx.cpp.
#
# Usage: m4 d3dxerr.w > d3dxerr.h
# m4 -Dswitch d3dxerr.w > d3dxerrswitch.h
