Returns a list of files matching a pattern.

Parameters:

pattern

file pattern

bool IsBinaryFile

(

const string

filename

)

[inline]

Check if a file exists and is a binary file.

Returns true if 'filename' is an existing binary file.

Parameters:

filename

path to file to test

bool IsBinaryFile

(

const char *

filename

)

Check if a file exists and is a binary file.

Returns true if 'filename' is an existing binary file.

Parameters:

filename

path to file to test

bool IsDirectory

(

const string

dirname

)

[inline]

Check if a directory exists.

Returns true if 'dirname' is an existing directory.

Parameters:

dirname

path to directory to test

bool IsDirectory

(

const char *

dirname

)

Check if a directory exists.

Returns true if 'dirname' is an existing directory.

Parameters:

dirname

path to directory to test

bool IsPowerOfTwo

(

unsigned int

x

)

[inline]

Is this integer a power of 2.

true is returned if this is the case.

Parameters:

x

integer to test.

bool IsTextFile

(

const string

filename

)

[inline]

bool ListDirectories	(	const string	maindir,
		vector< string > &	subdir
	)

Returns list of subdirectories.

The vector 'subdir' is filled with directories contained in 'maindir' Returns true if success

Parameters:

string ReplaceAll	(	string	str,
		const string &	from,
		const string &	to
	)

Replace all occurences of a sub-string.

All occurences of substring 'from' are replaced by 'to'. The modified string is returned.

Parameters:

	str	string to modify
	from	substring to replace from
	from	substring to replace to

vector<string> SplitString	(	const string	stringtodivide,
		const char	separator
	)

Splits a string.

A string is divided into an array of words. The separator defines where to break the string. The separator should be a single character. A vector of string is returned.

Parameters:

	stringtodivide	string to divide
	separator	separator
