Function Documentation

vtString ExtractPath	(	const char *	szFullPath,
		bool	bTrailingSlash
	)

Given a full path containing a filename, return a string containing just the path portion of the string.

Parameters

szFullPath	The full path.
bTrailingSlash	If true, include the trailing slash, if present. Example Input: "/usr/data/file.txt" Output: /usr/data/" with trailing slash, "/usr/data" without.

vtString FindFileOnPaths	(	const vtStringArray &	paths,
		const char *	filename
	)

This function will search for a given file on the given paths, returning the full path to the first file which is found (file exists and can be read from).

Parameters

paths	An array of strings containing the directories to search. Each directory should end with a the trailing slash ("/" or "\")
filename	A filename, which can optionally contain a partial path as well. Examples: "foo.txt" or "Stuff/foo.txt" Note: encoding of this filename is assumed to be UTF-8!

vtString GetExtension	(	const vtString &	fname,
		bool	bFull
	)

Get the full file extension(s) from a filename.

bool PathIsAbsolute

(

const char *

szPath)

Return whether a path is absolute or relative.

vtString PathLevelUp

(

const char *

src)

Given a path like "C:/bar/foo", returns the path a level up, like "C:/bar"

void RemoveFileExtensions	(	vtString &	fname,
		bool	bAll
	)

Given a filename (which may include a path), remove any file extension(s) which it may have.

const char* StartOfFilename

(

const char *

szFullPath)

Given a full path containing a filename, return a pointer to the filename portion of the string.

bool vtCreateDir

(

const char *

dirname)

Recursive make directory. Aborts if there is an ENOENT error somewhere in the middle.

Parameters

dirname

The full page to directory to be created, in utf-8 encoding.

Returns

true if OK, false on error

void vtDeleteFile

(

const char *

filename)

Delete a file.

void vtDestroyDir

(

const char *

dirname)

Destroy a directory and all its contents (recusively if needed).

FILE* vtFileOpen	(	const char *	fname_utf8,
		const char *	mode
	)

Open a file using a UTF-8 encoded filename.

Parameters are the same as fopen(). The only difference is that instead of being limited to multi-byte local charset, it is UTF-8 which supports all languages.

FILE* vtFileOpen	(	wchar_t *	fname_wide,
		const char *	mode
	)

Open a file using a wide-character (i.e. Unicode) filename.

Parameters are the same as fopen(). The only difference is that instead of being limited to multi-byte local charset, it is Unicode which supports all languages.
