Functions | |
| void | copy (const std::string &from, const std::string &to) |
| Copies files or directories. More... | |
| std::string | cwd () |
| Returns the current working directory, resolving symlinks. | |
| void | create_directory (const std::string &dir, double wait_time=1, size_t num_tries=40) |
Creates a directory, including any parents that don't exist. If the directory exists create_directory does nothing. More... | |
| bool | check_if_dir_exists (const std::string &dir) |
| Returns true if the directory exists. More... | |
| bool | check_if_file_exists (const std::string &file) |
| Returns true if the regular file or link to the regular file exists. More... | |
| size_t | file_size (const std::string &file) |
| Returns the file size in bytes. More... | |
| std::string | get_absolute_path (const std::string &rel_path) |
| Get the absolute path, resolving symlinks. More... | |
| std::string | get_file_name (const std::string &file_path) |
| Given a path to a file returns the file name. More... | |
| std::string | get_parent_path (const std::string &path) |
| Wraps the dirname function to get the pathname of the parent directory. More... | |
| std::vector< std::string > | glob (const std::string &pattern) |
| Get a list of files matching the given glob pattern. | |
| bool | is_file (const std::string &path) |
| Returns true if the path points to a regular file or a link to a regular file. More... | |
| std::vector< std::string > | ls (const std::string &dir_name="./") |
| Gets a list of files in a directory. More... | |
| void | rm (const std::string &path, bool recursive) |
| Deletes a file or directory. More... | |
A light-weight file system library based on POSIX.
We use this library instead of a subprocess based library because OpenMPI does not support forking of processes on all systems. Since the parallelization library we use may be implemented on top of OpenMPI we take the safe route and use POSIX.
