Checking a structure field ...

[James Ladd]

I have the following ...

Code Select Expand


local events:WSANETWORKEVENTS


and I need to see if the iErrorCode element at FD_ACCEPT is zero (0).
eg:  .if iErrorCode[FD_ACCEPT_BIT] == 0

Code Select Expand


FD_ACCEPT_BIT                   equ 3
FD_MAX_EVENTS                   equ 10
WSANETWORKEVENTS STRUCT
    lNetworkEvents              dd  ?
    iErrorCode                  dd  FD_MAX_EVENTS dup (?)
WSANETWORKEVENTS ENDS


I have tried the following without success ... :(

Code Select Expand


    mov eax, addr events


and

Code Select Expand


    mov eax, offset events


I just get MASM errors like invalid operand for offset or syntax error addr.

Your help would be appreciated.

James,

Just use LEA on the LOCAL structure name.
