31 /*--------------------------------DESCRIPTION-------------------------------
32 This module contains the code to see if players are allowed to play
33 depending on the time of day. This is done with a matrix that contains
34 an element for each hour in each day of the week. If the element is zero,
35 access is not allow. If it is not, then access is allowed. The time_access
36 function is called to check the time and look up the time in the access
37 matrix.
38 Before the time_access function is called, the load_time_access function
39 needs to be called. This function loads the access matrix from a file.
40 The format of the file is:
41 udfgaergfhggdfhg --These are three garbage lines
42 sdjkhgfsadhghsdghdgh --They are ignored
43 fjishgfsdhgdfhjghdahgdtu
44 SUN 0 0 0 0 1 1 1 ... --name of day followed by 24 0's or 1's
45 MON 0 1 1 1 1 ... -- 0 = closed 1 = open
46 The time_access function checks the time access matrix to see if access
47 should be allowed. The function makes a provision for overriding the
48 access matrix. If the file OVERRIDE exists, then access is automaticly
49 allowed. If the file DENY exists then access is disallowed. If they both
50 exists then access is allowed.
