Be sure you are using the fifth edition of the manual (April 1994).
The previous edition had numerous errors in the sample C code (documented
in SR 5003101402).
 
If you are having trouble with alignment, check out Engineering Note
W1680208, "Solving the alignment problem when accessing IMAGE from C/XL",
available on SupportLine or from the Response Center.  That EN contains
a complete sample program that you might find useful.  It demonstrates
one technique for getting around alignment mismatches.  Another technique
would be use use #pragma HP_ALIGN MPE_16 and the +u compiler option.
