help regarding wprintstr( )

Hi group,

I am using motorola microcontroller for my project. In one of the
sample projects I have seen a function wprintstr, which is not defined
in any of the projects (so a library function i suppose). It was not
listed in the codewarrior help. While searching in google i found that
,in C it prints a 16 bit word( I am not sure if it is defined by user
for that project or there in C compiler) . The exact occurence is as
follows:

if defined( WIN32 )
      WPRINTSTR( pkt->cmd.Data );

I understand that it prints Data but to where? Has that got anything to
do with WIN32 scripting? 
Can any one help me???

Thanks
Sri
