Detailed Description

Integer types with guaranteed sizes.

On the 65816 CPU (cproc compiler):

• char = 8 bits
• short = 16 bits
• int = 32 bits (4 bytes)
• long = 64 bits (8 bytes — NOT 32-bit!)

Always use these typedefs instead of C primitive types.

Typedef Documentation

s16

typedef signed short s16

16-bit signed integer (-32768 to 32767)

s32

typedef signed int s32

32-bit signed integer (-2147483648 to 2147483647)

Note

Uses int because cproc treats int as 32-bit on 65816.

s8

typedef signed char s8

8-bit signed integer (-128 to 127)

u16

typedef unsigned short u16

16-bit unsigned integer (0 to 65535)

u32

typedef unsigned int u32

32-bit unsigned integer (0 to 4294967295)

Note

Uses int because cproc treats int as 32-bit on 65816.

u8

typedef unsigned char u8

8-bit unsigned integer (0 to 255)
