boost::filesystem::exists crashs

问题:

I'm using boost 1.52, when i'm trying to get a file from a network drive that i don't have permissions to read from. I get an exception, after using boost::filesystem::exists(fileName)
Is there a work around nicer than just doing try, catch at every place?

I have switched back for my old code for now:

bool FileExists(const char* fileName) {     struct stat my_stat;     return (stat(fileName, &my_stat) == 0); }  //boost Exists throws exception if there are no permissions for share folder bool FileExists(const std::string& fileName) {     return FileExists(fileName.c_str()); } 

回答1:

Use the overload that does not throw.

bool exists(const path& p, system::error_code& ec) noexcept; 

You will want to check the output parameter however, so this may be more work than catching an exception. It depends what you're trying to accomplish.
