Such a file should contain a single line with a non-negative decimal
integer. pcf_getcount() reads the file and returns the value,
pcf_inccount() increases the number in the file by the specified amount.
A non-existent file is treated as a file containing the number zero.
The routines are safe against concurrent access.
