arch_htonl()

arch_htonl

(

)

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()

arch_htons

(

)

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()

arch_ntohl

(

)

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()

arch_ntohs

(

)

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()

arch_swap16

(

)

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()

arch_swap32

(

)

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.
