Detailed Description

The environment class provides methods for accessing and manipulating environment variables.

Member Function Documentation

static bool environment::clear ( ) [static]

Clears the environment of all name-value pairs. After calling this, variables() will return NULL.

static const char* environment::getValue ( const char * variable ) [static]

Returns the value of "variable".

static void environment::print ( ) [static]

Prints the environment variable list to stdout.

static bool environment::remove ( const char * variable ) [static]

Removes "variable" from the environment.

static void environment::setMutex ( mutex * mtx ) [static]

Allows you to supply a mutex if the class needs it. If your application is not multithreaded, then there is no need to supply a mutex.

static bool environment::setValue	(	const char *	variable,
		const char *	value
	)		`[static]`

Sets the value of "variable" to "value", overwriting any value that "variable" previously had. Returns true on success and false on failure.

static const char* const environment::variables ( ) [static]

Returns a NULL terminated list of all environment variables. Each entry in the list is of the form NAME=VALUE.
