Function Documentation

CreateDirectories()

bool amrex::FileSystem::CreateDirectories	(	std::string const &	path,
		mode_t	mode,
		bool	verbose = false
	)

Create a directory and any missing parent directories.

Parameters

path	directory path to create
mode	requested permissions for newly-created directories on POSIX platforms; ignored on Windows
verbose	print a diagnostic message when directory creation fails

Returns

true if the directory already existed or was created without error, false if directory creation failed. This differs from the return value of std::filesystem::create_directories, which is true only when a directory was actually created and false both when the directory already existed and when creation failed with an error.
