Define Documentation

#define ltoh16

(

l

)

htol16(l)

Converts a 16-bit integer to host byte order.

Use this function on variable values instead of the macro LTOH16(). This saves code size.

Parameters:

[in]

l

A 16-bit integer in little-endian byte order.

Returns:

The given 16-bit integer converted to host byte order.

HTOL16(val)

Converts a 16-bit integer to host byte order.

Use this macro for compile time constants only. For variable values use the function ltoh16() instead. This saves code size.

Parameters:

[in]

val

A 16-bit integer in little-endian byte order.

Returns:

The given 16-bit integer converted to host byte order.

Definition at line 84 of file byteordering.h.

#define ltoh32

(

l

)

htol32(l)

Converts a 32-bit integer to host byte order.

Use this function on variable values instead of the macro LTOH32(). This saves code size.

Parameters:

[in]

l

A 32-bit integer in little-endian byte order.

Returns:

The given 32-bit integer converted to host byte order.

(

val

)

HTOL32(val)

Converts a 32-bit integer to host byte order.

Use this macro for compile time constants only. For variable values use the function ltoh32() instead. This saves code size.

Parameters:

[in]

val

A 32-bit integer in little-endian byte order.

Returns:

The given 32-bit integer converted to host byte order.
