getfcycle - get time cycle names
Getfcycle returns a pointer to an array of 4 character pointers.
Each of these pointers point to a null terminated string
corresponding to the names of each cycle of time (AM, PM, Noon &
Midnight). These values are used by fatotime(C-3) when an
arbitrary time is entered (not matching the format parameter).
Thus, the format can be: HH:mm:ss and 1Pm could be entered as a
valid time (assuming the default formatting set).
The cycle names are retrieved from the country format structure
fcountry(C-3), fatotime(C-3), atotime(C-3)
