C to PB help

[Doug McDonald]

Can "C" guru here please take a look at the following code translation and
see if there is an error. Thank you

'***** C CODE **************************************
'void Upload( void *loadDat, unsigned int ULSize )
'void *DownLoad( unsigned int request_size)

'char request[] = “\5\0\2\0\0\16\0\0”;
'Upload( request, 8 );

'char *response = DownLoad( 4096 );
'void *DownLoad( unsigned int request_size)

'***************************************************

'******* PB translation ? ***************************
'DECLARE SUB UpLoad LIB "pigusb_test.DLL" ALIAS "UpLoad" (BYVAL loadDat AS DWORD,BYVAL ULSize AS DWORD)
'DECLARE FUNCTION DownLoad LIB "pigusb_test.DLL" ALIAS "DownLoad"(BYVAL request_size AS DWORD) AS DWORD

LOCAL request AS STRING
request = CHR$(5,0,2,0,0,16,0,0)
upload ( STRPTR(request), 8)

LOCAL response AS ASCIIZ PTR
response = DownLoad(4096)
CONTROL SET TEXT hDlg, %IDC_TEXTBOX1, STR$(response ) 'see if I get the ptr

Use the following:

CONTROL SET TEXT hDlg, %IDC_TEXTBOX1, @response

Thank you Jose,

Does the C to Pb porting Look ok? Data types match up, call correct ect...?

Thanks again

The parameters look correct. However, you will have to add CDECL to
the PB declarations.

Surely that would depend on the calling convention setting specified in the C "project file"?

Um, then I gotta ask... why are you using this code?

Surely there is some quality "download" code available here at the right price (free).

(Textbook example of why I detest "verb-for-verb" translations from other programming languages).
