Hello,
in Masm I can use:
fName db '\??\D:\Sysenter.txt',0 ;// name of file
fLen = $ - fName ;// len of name
but Poasm not. What is right way? I tried this:
fName db "\??\D:\Sysenter.txt",0
fLen SIZESTR "\??\D:\Sysenter.txt"
because fLen SIZESTR fName returned 0x5
Hi bitcoin,
The $ operator has another meaning in Poasm. Reading the manual :
QuoteAssembler identifiers (IA32, AMD64)
You cannot use keywords as identifiers. You can however escape a keyword, by prefixing it with a $ character, to force POASM to handle it as an identifier.
Examples :
.
.
$fastcall ; will be forced as identifier fastcall, not keyword fastcall
A simple macro can do the job :
.386
.model flat,stdcall
option casemap:none
ExitProcess PROTO :DWORD
printf PROTO C :DWORD,:VARARG
includelib \PellesC\lib\Win\kernel32.lib
includelib msvcrt.lib
DefStr MACRO id,str
.data
id db str
db 0
slen SIZESTR str
.code
ENDM
.data
msg db 'Lenght of the string = %u',0
.code
start:
DefStr string,"Hello world!"
invoke printf,ADDR msg,slen
invoke ExitProcess,0
END start
EDIT : I added the missing file msvcrt.def to the attachment.
Hi bitcoin,
Another attempt without macros :
.386
.model flat,stdcall
option casemap:none
ExitProcess PROTO :DWORD
printf PROTO C :DWORD,:VARARG
includelib \PellesC\lib\Win\kernel32.lib
includelib msvcrt.lib
.data
string db 'Hello world!'
nullterm db 0
slen EQU OFFSET nullterm - OFFSET string
msg db 'Lenght of the string = %u',0
.code
start:
invoke printf,ADDR msg,slen
invoke ExitProcess,0
END start
Thank you Vortex !
