Byte-order management for the SH4 architecture

Macro Definition Documentation

BYTE_ORDER

#define BYTE_ORDER   LITTLE_ENDIAN

Define the byte-order of the platform in use.

Function Documentation

arch_htonl()

static uint32_t arch_htonl ( uint32_t x )

inlinestatic

Convert host-to-network long.

This macro converts a value in the host's native byte order to network byte order (big endian). On a little endian system (like the Dreamcast), this should just call arch_swap32(). On a big endian system, this should be a no-op.

Parameters

x	The value to be converted. This should be a uint32, or equivalent.

Returns

The converted value.

arch_htons()

static uint16_t arch_htons ( uint16_t x )

inlinestatic

Convert host-to-network short.

This macro converts a value in the host's native byte order to network byte order (big endian). On a little endian system (like the Dreamcast), this should just call arch_swap16(). On a big endian system, this should be a no-op.

Parameters

x	The value to be converted. This should be a uint16, or equivalent.

Returns

The converted value.

arch_ntohl()

static uint32_t arch_ntohl ( uint32_t x )

inlinestatic

Convert network-to-host long.

This macro converts a network byte order (big endian) value to the host's native byte order. On a little endian system (like the Dreamcast), this should just call arch_swap32(). On a big endian system, this should be a no-op.

Parameters

x	The value to be converted. This should be a uint32, or equivalent.

Returns

The converted value.

arch_ntohs()

static uint16_t arch_ntohs ( uint16_t x )

inlinestatic

Convert network-to-host short.

This macro converts a network byte order (big endian) value to the host's native byte order. On a little endian system (like the Dreamcast), this should just call arch_swap16(). On a big endian system, this should be a no-op.

Parameters

x	The value to be converted. This should be a uint16, or equivalent.

Returns

The converted value.

arch_swap16()

static uint16_t arch_swap16 ( uint16_t x )

inlinestatic

Swap the byte order of a 16-bit integer.

This macro swaps the byte order of a 16-bit integer in an architecture- defined manner.

Parameters

x	The value to be byte-swapped. This should be a uint16, or equivalent.

Returns

The swapped value.

arch_swap32()

static uint32_t arch_swap32 ( uint32_t x )

inlinestatic

Swap the byte order of a 32-bit integer.

This macro swaps the byte order of a 32-bit integer in an architecture- defined manner.

Parameters

x	The value to be byte-swapped. This should be a uint32, or equivalent.

Returns

The swapped value.
