最近需要通过smbus来读取一些信息,但是在一些机器上smbus好像被隐藏了.我google了好久就找到了一个linux内核得patch;我刚开始学习linux所以麻烦各位大牛解释一下 我想知道得是pci_read_config_word(dev, 0xF2, &val);读取得是这个设备得什么信息? 劳烦各位指点一下;不胜感激; Asus hides the smbus PCI bridge within the ICH2 or ICH4 southbridge on Asus P4B/P4PE mainboards.

代码大致如下： use strict; use warnings; my $total = 0; foreach () {    my $temp=function($_); #接收一个函数的返回值        $total += $temp; } print "$total"; 运行的时候提示警告： Use of uninitialized value in addition (+) at..... 就是$total += $temp那一行 请问要怎么改才能不出现这个警告？不要告诉我是注释use warning:wink:

写了一段代码，如下： #!/usr/bin/perl -w open (NEWTXT, "C:/Documents and Settings/Administrator/My Documents/新建文本文档.ascii")||die "Cannot open this file:$!"; open (OUTPUT, ">C:/Documents and Settings/Administrator/My Documents/输出.ascii")||die "Cannot open the file match_Yeast_A1:$!"; @array=; foreach $array (@array) {if ($array=~/(\d+), (\d+)/) {$RT=$1; $intensity=$2;} print OUT...

用CPAN上的LIBSVM工具包,出现这个错误!!!!不知是为什么?哪位高人见过这个问题. 这条警告信息会在什么条件下产生啊? #!/usr/bin/perl -w use strict; use Algorithm::SVM; my $svm=Algorithm::SVM->new();

my code is: if (($telephon[$m] =~ /^\s+$/) ||($telephon[$m] =~ /^\*/) || ($telephon[$m] !~ /^\(/)) {next; } Result: Use of uninitialized value in pattern match (m//) at select.pl line 53. why??????????

下面程序在linux fc7 下用gcc编译 #include #include #include #include #include #include main(int argc,char * argv[] ) { int fd1,fd2,l; void * tp; char *path; char buf[50]; struct stat ps; path=buf; printf("enter a path:"); scanf("%s",path); printf("%s",argv[1]); fstat(fd1.&ps); if(fd1=(open(argv[1],O_RDONLY))==-1) {printf("error1");exit(1);}...

我在用户的crontab里加了这样一个脚本： 1 * * * * sh /usr/local/bin/cron880_sqwen.sh >; /dev/null & 之后系统总是向我发这样的mail: Your "cron" job on sqwen sh /usr/local/bin/cron880_sqwen.sh >; /dev/null & produced the following output: stty: : No such device or address stty: : No such device or address 请问是怎么回事啊？ 难道我的/dev/null不存在吗？可明明有的啊
