how to use c standard i/o in masm?

[t3dbundy]

like this:
invoke printf,....?

but it has assembly error:

undefined symbol : printf

[hutch--]

Ted,

Give the MSVCRT library a try, there are both includes and a library for it but not that the formatting for printf will not work without a C compiler as it is not part of the library routine.

t3dbundy,

You should convert C formattings like the following :

Code Select Expand

char format1[]="%s\n";

to

Code Select Expand

format1 db '%s',13,10,0

[t3dbundy]

use like this?

Code Select Expand


.386
.model flat,stdcall
option casemap :none

include windows.inc
include msvcrt.inc
include kernel32.inc
includelib kernel32.lib
includelib msvcrt.lib

.data
format db '%d',0

.code
start:
invoke crt_printf,addr format,67
invoke ExitProcess,NULL
end start

but,it print nothing in console.

Did you specify the subsystem as console?

Code Select Expand

link /SUBSYSTEM:CONSOLE srcfile.obj
