The LP64 model is used not the IPL64 model so: $ ./sizes32 sizeof(size_t) = 4 sizeof(ssize_t) = 4 sizeof(off_t) = 4 sizeof(boolean_t) = 4 sizeof(uint8_t) = 1 sizeof(uint16_t) = 2 sizeof(uint32_t) = 4 sizeof(uint64_t) = 8 sizeof(int8_t) = 1 sizeof(int16_t) = 2 sizeof(int32_t) = 4 sizeof(int64_t) = 8 sizeof(unsigned char) = 1 sizeof(char) = 1 sizeof(char*) = 4 sizeof(short) = 2 sizeof(int) = 4 sizeof(unsigned int) = 4 sizeof(long) = 4 sizeof(unsigned long) = 4 sizeof(long long) = 8 sizeof(double) = 8 sizeof(float) = 4 sizeof(void*) = 4 $ ./sizes64 sizeof(size_t) = 8 sizeof(ssize_t) = 8 sizeof(off_t) = 8 sizeof(boolean_t) = 4 sizeof(uint8_t) = 1 sizeof(uint16_t) = 2 sizeof(uint32_t) = 4 sizeof(uint64_t) = 8 sizeof(int8_t) = 1 sizeof(int16_t) = 2 sizeof(int32_t) = 4 sizeof(int64_t) = 8 sizeof(unsigned char) = 1 sizeof(char) = 1 sizeof(char*) = 8 sizeof(short) = 2 sizeof(int) = 4 ### Note this int == int32_t sizeof(unsigned int) = 4 sizeof(long) = 8 sizeof(unsigned long) = 8 sizeof(long long) = 8 sizeof(double) = 8 sizeof(float) = 4 sizeof(void*) = 8 -- Darren J Moffat
