Function Documentation

compareFileName() [1/2]

int libxcks::compareFileName	(	const std::filesystem::path &	p1,
		const std::filesystem::path &	p2
	)

Compares file names of two paths.

Under Windows the comparison is case insensitive.

Parameters

p1	First path.
p2	Second path.

Returns

A negative value if f1 < f2, a positive value if f1 > f2, 0 if f1 == f2.

Definition at line 137 of file pathutil.cpp.

compareFileName() [2/2]

int libxcks::compareFileName	(	const std::string &	fn1,
		const std::string &	fn2
	)

Compares two file names.

Under Windows the comparison is case insensitive.

Parameters

fn1	First file name.
fn2	Second file name.

Returns

A negative value if f1 < f2, a positive value if f1 > f2, 0 if f1 == f2.

constructPath()

std::filesystem::path libxcks::constructPath	(	const ArrayString &	dirs,
		const std::string &	filename
	)

Constructs a path from an array of directories and an optional filename.

Parameters

[in]	dirs	The array of directories.
[in]	filename	The filename. Can be empty.

Returns

The constructed path.

ensureEndsWithPathSeparator()

std::filesystem::path libxcks::ensureEndsWithPathSeparator

(

const std::filesystem::path &

p

)

Ensures the path ends with a path separator.

Warning

This function does not check the type of the path (directory, file, or others).

Parameters

[in]

p

The path to ensure it ends with a path separator.

Returns

The path with a path separator at end.

getDirectories()

std::vector< std::filesystem::path > libxcks::getDirectories

(

const std::filesystem::path &

p

)

Gets directories of a path.

Parameters

[in]

p

The path the directories are wanted.

Returns

The directories in path vector form.

Definition at line 64 of file pathutil.cpp.

getDirectoriesAsArrayString()

ArrayString libxcks::getDirectoriesAsArrayString

(

const std::filesystem::path &

p

)

Gets directories of a path.

Parameters

[in]

p

The path the directories are wanted.

Returns

The directories in path vector form.

Definition at line 81 of file pathutil.cpp.

isFileNameValid()

bool libxcks::isFileNameValid

(

const std::string &

filename

)

Checks if the name of the file is valid.

The name of the file to check must be a full name (including extension but excluding directories).

The forbidden characters are:

• On Unix: / (forward slash) and NUL byte.
• On Windows: https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file
  • < (less than)
  • > (greater than)
  • : (colon)
  • " (double quote)
  • / (forward slash)
  • \ (backslash)
  • | (vertical bar or pipe)
  • ? (question mark)
  • * (asterisk)
  • NUL byte
• On Mac: / (forward slash), : (colon) and NUL byte (even if this one is officially supported).

On Windows the following is also considered as invalid:

• bytes 1 to 31 (ASCII control characters)
• the following reserved name of file (case insensitive):
  • CON, PRN, AUX, NUL
  • COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8 and COM9
  • LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8 and LPT9
• Names of file ending with a space or a dot.

An empty name is invalid.

The full names . and .. are also invalid on Unix and Windows.

Parameters

filename

The name of file to check (see upper).

Returns

true if the name of file is valid on the current OS, false otherwise.
