Function Documentation

string configurationDirectory

(

char *

directory = NULL

)

Returns the configuration directory read from the config.h created during configure - default: '/etc/dreamcache'.

Pass argc and argv from the main() function to let user overwrite it.

Parameters:

directory

pass configuration directory path to override the default

Definition at line 139 of file functions.cpp.

double diffTimes	(	timeval *	t1,
		timeval *	t2
	)

Calculates the difference between two given moments in time.

Returns:

the difference in seconds

Definition at line 15 of file functions.cpp.

int extractValue	(	const string &	s,
		unsigned	offset,
		const string &	confFilename,
		int	line
	)			throw (ConfigSemanticException)

Reads an integral value from the offset position of the string s and ensures there is no further input in s.

Extract numeric value from the given string.

Parameters:

	s	Read string
	offset	position of the value to be read
	confFilename	Configuration file currently parsed
	line	Line of the configuration file currently parsed

Returns:

Parsed integer

Exceptions:

ConfigSemanticException

When there is no integer at given position.

string getPackageName

(

)

Returns the package name from the config.h created during .

/configure - default: 'dreamcache'

Definition at line 154 of file functions.cpp.

ostream& operator<<	(	ostream &	out,
		map< int, char > &	mymap
	)

Writes the given map to the out output.

Parameters:

	out	the output
	mymap	the map

Definition at line 128 of file functions.cpp.

template<typename T, typename L>

ostream& operator<<	(	ostream &	out,
		pair< T, L > &	p
	)			[inline]

Writes the given pair of objects to the out output.

Parameters:

	out	the output
	p	the pair

Definition at line 124 of file functions.cpp.

std::string removeBlanks

(

string

s

)

Trims given string from left and right side and throwing out the comment (starting in #).

Parameters:

s

Input string

Returns:

string without a comment and whitespaces at both ends

Definition at line 38 of file functions.cpp.

bool safe_strtoull	(	const char *	str,
		uint64_t *	out
	)

Checks whether the given string begins with a valid unsigned value and writes the value to the out parameter.

Parameters:

	str	string to extract the value from
	out	64-bit variable pointer where the value will be written
