获得完整的申请途径 [英] get full path of application
问题描述
大家好，
我现在很困惑。我如何获得应用程序的完整路径？
如果myapp位于属于PATH的目录中，argv [0]首先给我
cmd行的标记，而不是执行的
程序的真实路径。
所以，如果我在任何地方写：
％myapp
它从文件中运行正常（例如）/ usr / local / bin / myapp
但是argv [ 0]给我回报
../myapp
但我需要
/ usr / local / bin / myapp
提前感谢
hi all,
i''m confused now. how i can get the full path of an application?
if myapp is in a directory which belongs to PATH, argv[0] gives me the
first token of cmd line, and not the real path of the executed
program.
so if i write anywhere:
% myapp
it runs ok from the file (for example) /usr/local/bin/myapp
but argv[0] returns me
../myapp
but i need
/usr/local/bin/myapp
thanks in advance
