Google 开源了 google-gflags 库,这是一个命令行标志解析库。 AFAIK
,它不提供每个标志的“长和短”版本(因此您不能组合多个选项“-aeiou”),但使用起来很简单,并且不需要集中的标志列表。
Google has open sourced the google-gflags library, a command line flag parsing library..
AFAIK, it doesn't provide a "long and short" version of each flag (so you can't combine in multiple options "-aeiou"), but it's trivial to use and doesn't require a centralized list of flags.
getopt_long 可以完成这项工作,这里是一个例子http://www.gnu.org/s /libc/manual/html_node/Getopt-Long-Option-Example.html
getopt_long will do the job, here is an example from http://www.gnu.org/s/libc/manual/html_node/Getopt-Long-Option-Example.html
GNU 提供
getopt_long
,尽管他们实际上推荐argp
。查看 GNU libc 手册 解析参数的条目。GNU provides
getopt_long
, though they actually recommendargp
. Check out the GNU libc manual entry on parsing arguments.http://argtable.sourceforge.net/

过去,人们只是将
getopt.c
和getopt.h
与其源代码一起打包。这是Google 代码查询。如果您不想依赖 GNU libc,则可以使用它,因为您可能在不同的操作系统上需要它。但是,如果您使用的是 Linux,那么 libc 已经按照其他答案的建议将其提供给您。
Back in the day people just packaged
getopt.c
andgetopt.h
with their sources.Here is a Google Code query for it. You could use that if you do not want to depend on GNU libc because you may need this on a different OS. But if you're on Linux then libc already gives it to you as the other answers suggested.
