在Mac OS X上,/proc/self/cmdline/GetCommandLine等效项是什么?
如何在不使用argc,argv的情况下访问Mac OS X上的命令行?在Linux上,我只读/proc/self/cmdline
或在Windows上使用GetCommandLine
,但找不到与Mac OS X等效的文件.
How can I access the command line on Mac OS X without using argc, argv? On Linux, I would simply read /proc/self/cmdline
or use GetCommandLine
on Windows, but I can't find the equivalent for Mac OS X.
There are functions called _NSGetArgv and _NSGetArgc in crt_externs.h. However, wouldn't it be simpler to just store the argc/argv in a variable at the start of main and be portable to all three platforms?
注意:这些函数没有直接记录,但在 environ(7)联机帮助页.
NOTE: These functions are not directly documented, but they are mentioned in the documentation for NSApplicationMain in the Application Kit Functions Reference, and the related _NSGetEnviron is mentioned in the environ(7) manpage.
