pointer to struct

[aloha_arts]

how can i define a procedure that fills up a structure with some string fields in masm,
provided that the procedure invokes some other functions to fill each field?

i need to call the procedure from c.

example:

Code Select Expand


MYSTRUCT STRUCT
    str1 BYTE 10 dup(?)
    str2 BYTE 10 dup(?)
MYSTRUCT  ENDS


myproc PROC STDCALL pMyStruct:DWORD
    push ebx
   
    lea  ebx, pMyStruct
   
    invoke  FillStringProcedure, addr [ebx].MYSTRUCT.str1
    invoke  FillStringProcedure, addr [ebx].MYSTRUCT.str1

    pop ebx
    ret
myproc endp



FillStringProcedure fills up a string from a given pointer

thankyou.

Code Select Expand

lea  ebx, pMyStruct
this load the variables address, not the content (which is the pointer)
-->

Code Select Expand

mov ebx,pMyStruct
