Leer salida de un comando en MASM

[.:UND3R:.]

Hola a todos me gustaría saber como puedo leer la salida de un comando ejecutado en la consola, me explico:

Mi programa -> Lanza el comando cmd.exe -> el programa recibe en un buffer lo que mostró es decir:

Microsoft Windows XP [Versión 5.1.2600]

Tengo el siguiente código, solo tomen importancia en donde he comentado:

Código (asm) [Seleccionar] Expandir

lpCmdLine4 byte 100 dup(?)
lpCmdLine4_size byte ?

mov sattb.nLength,sizeof sattb
mov sattb.bInheritHandle,TRUE
mov sattb.lpSecurityDescriptor,NULL
invoke CreatePipe,addr hReadPipeOut,addr hWritePipeOut,addr sattb,0

invoke SetHandleInformation,hReadPipeOut,HANDLE_FLAG_INHERIT,NULL

mov eax,hReadPipeOut

mov sinfo.cb,sizeof sinfo
mov sinfo.dwFlags,STARTF_USESTDHANDLES
mov sinfo.hStdOutput,eax
mov sinfo.hStdOutput,eax
mov sinfo.hStdError,eax
invoke CreateProcess,NULL,addr lpCmdLine3,NULL,NULL,TRUE,0,NULL,NULL,addr sinfo,addr pinfo

invoke ReadFile,hReadPipeOut,addr lpCmdLine4,sizeof lpCmdLine4,addr lpCmdLine4_size,NULL
; ------ FIN DE LO QUE ESTOY INTENTANDO REALIZAR -----
invoke Sleep,1200000d
.ENDIF
.ENDW
main ENDP
END main

Problema: Luego de llamar a ReadFile nunca retorna y su buffer no contiene la salida de cmd.

A ver si me ayudan, saludos
