Steve, /usr/include/sys/types.h defines uid_t as a u_int32_t. /usr/include/sys/inttypes.h typedefs u_int32_t to __int32_t. /usr/include/machine/ansi.h typedefs __int32_t to int. So, uid_t is an int. sizeof( int ) on my 4.0-CURRENT machine is 4 bytes. 2^32 = 4294967296 So, I think thats how many UIDs we can have. Is that right everyone? If so, thats a lot of UIDs. -Ayan [ Quoted message from Steve Ames, recieved May 25, 1:24pm.] > > This is probably a silly question... how many UIDs can I have on a > single system?
