This function build a valid SQL-query. Some variables like u for user or c for column_password are substitutet by their meaning.

Parameters:

	command	In this char array the resulting query will be stored.

In this case you can fill this array with the values where value[0] corresponds to the first variable in the query, value[1] corresponds to the second variable in the query ... and so on.
	query	The original query which is not expanded yet thus the given variables arent substituted by their meaning.
	service	Service name character array.
	user	Character array which contains username/uid of the user that tries to change password - only for using password in a SQL-query.
	passwd	Password parameter - only for using passw in a SQL-query.
	rhost	Value of PAM_RHOST - only for using rhost in a SQL-query.
	raddr	Remote Address - the ip of rhost - only for using raddr in a SQL-query.
	options	Struct which represents exactly one database connection - only for using options in a SQL-query.
