Hello,

i don't know this api ..
but the parameter naming convention lead me to the idea that the lpLen* parameters are integers that indicate how big the buffers are you passed in in lpFront, lpBack & lpCode.

There are some functions in the normal Win32 Api that work the same.

you may try this:

DECLARE INTEGER BUICScan IN BUICAP32.DLL ;
INTEGER iJobType, ;
STRING @ lpFront, ;
INTEGER lpLenFront, ;
STRING @ lpBack, ;
INTEGER lpLenBack, ;
STRING @ lpCpode, ;
INTEGER lpLenCode

LOCAL lcFront, lnLenF, lcBack, lnLenB, lcCode, lnLenC, lnJobType

STORE SPACE(255) TO lcFront, lcBack, lcCode
STORE 255 TO lnLenF, lnLenB, lnLenC
lnJobType = whatever ..

? BUICScan(lnJobType,@lcFront,lnLenF,@lcBack,lnLenB,@lcCode,lnLenC)


just a guess .. but maybe it helps ..

if you would post the C declaration there will be enough people here to convert it easily.

Regards
Christian
