got it!
it should be enough to set O_NONBLOCK before reading and clear it afterwards. hehe, i'm posting 3 times in a row, might be some kind of disease  |

any ideas? |

I think here is right place to go:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/console_functions.asp as for non-blocking read from console, there is a C/C++ lib function _getch_nolock() as you can find in: http://msdn2.microsoft.com/zh-tw/library/236adc23.aspx |

chris: thanks, but i have studied console functions already. getc()_closk() is not what i want too, i know how to do that. problem is that getc_lock() still blocks when there is nothing in input buffer (from previous read).
anyway, it seems that win just doesn't support this. I can go without it, but this way my routines will be quite uneffective on win32. (well... little more effective than libc maybe). |

Not sure if this is what you want but heres some code:
Code: STD_INPUT_HANDLE equ 0xFFFFFFF6 ENABLE_LINE_INPUT equ 0x00000002 ;... hConI dd 0 Buffer rb 256 BufferSize dd ($ - Buffer) BytesRead dd 0 ;... invoke [hConI],GetStdHandle,STD_INPUT_HANDLE ; Get console handle mov [hConI],eax ; invoke SetConsoleMode,[hConI],ENABLE_LINE_INPUT ; Set input to line input ; This makes ReadConsoleA ; only return when the user ; presses enter invoke ReadConsoleA,[hConI],Buffer,BufferSize,BytesRead,NULL ; Read line into Buffer up to ; BufferSize bytes, put bytes ; written into BytesRead Or are you trying to do something else? |
