Global Functions¶

NGRAPH_API std::string get_file_name(const std::string& path)

Returns the name with extension for a given path.

Parameters:

path	The path to the output file

NGRAPH_API std::string get_file_ext(const std::string& path)

Returns the file extension.

Parameters:

path	The path to the output file

NGRAPH_API std::string get_directory(const std::string& path)

Returns the directory portion of the given path.

Parameters:

path	The path to the output file

NGRAPH_API std::string path_join(const std::string& s1, const std::string& s2)

Joins multiple paths into a single path.

Parameters:

s1	Left side of path
s2	Right side of path

NGRAPH_API void iterate_files(
    const std::string& path,
    std::function<void(const std::string&file, bool is_dir)> func,
    bool recurse = false,
    bool include_links = false
    )

Iterate through files and optionally directories. Symbolic links are skipped.

Parameters:

path	The path to iterate over
func	A callback function called with each file or directory encountered
recurse	Optional parameter to enable recursing through path

NGRAPH_API void convert_path_win_style(std::string& path)

Change Linux-style path (‘/’) to Windows-style (’')

Parameters:

path	The path to change file separator

NGRAPH_API std::string wstring_to_string(const std::wstring& wstr)

Conversion from wide character string to a single-byte chain.

Parameters:

wstr	A wide-char string

Returns:

A multi-byte string

NGRAPH_API std::wstring multi_byte_char_to_wstring(const char \* str)

Conversion from single-byte chain to wide character string.

Parameters:

str	A null-terminated string

Returns:

A wide-char string

NGRAPH_API std::string sanitize_path(const std::string& path)

Remove path components which would allow traversing up a directory tree.

Parameters:

path	A path to file

Returns:

A sanitiazed path
