fs_filename()

const char * fs_filename

(

const char *

path

)

Gets the name of a file or folder specified by a path, i.e. the last segment of the path.

path	Path from which to retrieve the filename.

Returns

Filename of the path.

Remarks

Supports forward and backward slashes as path segment separator.

No distinction between files and folders is being made.

char * fs_getcwd	(	char *	buffer,
		int	buffer_size
	)

Gets the current working directory.

Parameters

buffer	Buffer that will receive the current working directory.
buffer_size	Size of the buffer.

Returns

Pointer to the buffer on success, nullptr on failure.

Remarks

The strings are treated as zero-terminated strings.

fs_is_dir()

int fs_is_dir

(

const char *

path

)

Checks if a folder exists.

Parameters

path	the path to check.

Returns

1 if a folder with the given path exists, 0 on failure or if the folder does not exist.

Remarks

The strings are treated as zero-terminated strings.

fs_is_file()

int fs_is_file

(

const char *

path

)

Checks if a file exists.

Parameters

path	the path to check.

Returns

1 if a file with the given path exists, 0 on failure or if the file does not exist.

Remarks

The strings are treated as zero-terminated strings.

fs_is_relative_path()

int fs_is_relative_path

(

const char *

path

)

Checks whether a given path is relative or absolute.

Parameters

path	Path to check.

Returns

1 if relative, 0 if absolute.

Remarks

The strings are treated as zero-terminated strings.

fs_listdir()

void fs_listdir	(	const char *	dir,
		FS_LISTDIR_CALLBACK	cb,
		int	type,
		void *	user
	)

Lists the files and folders in a directory.

Parameters

dir	Directory to list.
cb	Callback function to call for each entry.
type	Type of the directory.
user	Pointer to give to the callback.

Remarks

The strings are treated as zero-terminated strings.

fs_listdir_fileinfo()

void fs_listdir_fileinfo	(	const char *	dir,
		FS_LISTDIR_CALLBACK_FILEINFO	cb,
		int	type,
		void *	user
	)

Lists the files and folders in a directory and gets additional file information.

Parameters

dir	Directory to list.
cb	Callback function to call for each entry.
type	Type of the directory.
user	Pointer to give to the callback.

Remarks

The strings are treated as zero-terminated strings.

fs_makedir()

int fs_makedir

(

const char *

path

)

Creates a directory.

Parameters

path	Directory to create.

Returns

0 on success. Negative value on failure.

Remarks

Does not create several directories if needed. "a/b/c" will result in a failure if b or a does not exist.

The strings are treated as zero-terminated strings.

fs_makedir_rec_for()

(

const char *

path

)

Recursively creates parent directories for a file or directory.

Parameters
