Function Documentation

generate_password()

bool generate_password	(	char *	password,
		int	size
	)

initialize_create_data_directory()

bool initialize_create_data_directory

(

const char *

data_home

)

Create the data directory.

Creates the data directory when –initialize is specified. The directory is created when it does not exist. If it exists, is empty and the process can write into it no action is taken and the directory is accepted. Otherwise an error is thrown.

Parameters

data_home

the normalized path to the data directory

Returns

status

Return values

true	failed to create. Error printed.
false	success
