发帖数: 117 | 2 Seems setitimer() can be used only one in a process.
and 1/1000 is not precise enough for a timer.
looking at linux real time implementation.
want to know the last news about the POSIX 1.b implement on
linux.
would you please give me some iformation?
since I can not find even at the last 2.4.0 kernel.
the kernel.org can only dl the souce code no much
information
gaven.
Thanks |

发帖数: 30 | 3 Normally when we say sh, we mean Bourne Shell. It appeared
from the Seventh Edition Bell Labs Research version of UNIX.
Bash is an sh-compatible shell that incorporates useful
features
from the Korn shell ksh and the C shell csh. It is intended
to
be a conformant implementation of the IEEE POSIX Shell and
Tools
specification (IEEE Working Group 1003.2). It offers
functional
improvements over sh for both interactive and programming
use.
Nowadays, it currently runs on nearly every versino of Unix |

I mean POSIX thread. pthread_kill seems to work for Solaris thread. |

发帖数: 4406 | 5 I do not know why these guys are focused on those
crappy GUI stuff rather than give a better support
on those basic posix api. All the signal related
API are problematic, even fork have very different
behaviour from UNIX platforms.
As for XFree, it is no match for windows
even in its native platform, how can one expect it
to outperform windows on CYgWin? |

Read never returns ENOENT, at least no POSIX systems. So something very wrong
is there. |

Term::ReadKey handles all the complex for you, so you can write several
lines of code to fulfill your task.
It is much difficult to do your own, but it is possible. check POSIX
module, and basically you write it as C code. |

发帖数: 192 | 10 I hope to know the behaviors of several POSIX threads in the same process,
any function I can use? Thank you! |

要交project,
本来觉得很简单的问题，想着半天就应该做出来，
可逐渐发现现有的 packages 都不完全合适
a distributed algorithm protocol implementation
3 phase commit,
I need to show the effect of message delay ,so
I need to introduce artificial delay to real API xxx_send
I do this by spawning a POSIX thread, and then
do usleep() and XXX_send in that thread,
I use PVM for different processes, this is an overkill
but very easy to use because PVM has timed recv, ( I need timeout
in the protocol, and i |

具一样的。Linux用的那些apt-get可能是别的一套。MacOSX的图形界面不一样，除非你
非要用X做界面。 |

发帖数: 734 | 17 If you really need to handle general signals using native Fortran,
you will need a compiler that supports the PXFSIG* subroutines
defined in the POSIX Fortran binding standard IEEE 1003.9-1992.
It might be easier to use mixed Fortran/C++ compilation to do
what you want, if your compiler supports mixed language calling.
If you only want to deal with numerical exceptions, check whether
your compiler supports the Fortran 2003 ieee_exceptions intrinsic
module. |

发帖数: 121 | 19 My two cents. I'm not from a CS background so I might be in a similar
situation with you.
If you want to do multithreading programming in C++, you can look up the
boost Thread library and here's the link.
http://www.boost.org/doc/libs/1_42_0/doc/html/thread.html
I personally feel that it's a lot easier to use the boost library compared
to the POSIX pthread library. And for most purposes this is good enough. Of
course you'll need to know some of the basic concepts in multithreading such
as thread |

通用的UNIX程序都可以移植过来。
>> 微内核结构(最小结构<8KB)
hmm... vxWorks is smaller, but can't be called "microkernel". MicroKernel
has special meaning. http://en.wikipedia.org/wiki/Microkernel. QNX is microKernel even it is bigger than the smallest vxWorks. hehe.
>>包括多任务调度采用优先级抢占方式
For RTOS, this is bad. hehe.
