/****************************************************************************
* OS/2 Sample Print Application PRTSAMP
*
* name: pmassert.h
*
* description: similar to C assert.h, but presents debugging information
* in a PM message box instead of standard error.
*
* The pmassert macro works when the symbol NDEBUG is not defined to the
* compiler; thus, the macro works by default.
*
* To build a non-debug version of the program, define the symbol NDEBUG
* with the proper compiler switch, usually /DNDEBUG
*
* The message box shows the last error in hex. The high word is severity,
* and the low word is an error code. Refer to pmerr.h for an explanation
* of the error code.
*
* Do not pmassert any assignment statements or function calls, for these
* statements will vanish in the non-debug version of the code. Assert only
* Boolean expressions you think should always be true.
*
