NAME
u32_le, u32_be, u32p_le, u32p_be - convert an u32 to little/big endian
u32pa_le, u32pa_be - convert an array of u32 into little/big endian
SYNOPSIS
#include <limb/u32.h>
u32 u32_le(u32 u) u32 u32_be(u32 u) void u32p_le(u32 *val) void u32p_be(u32 *val) void u32pa_le(u32 *val, size_t len) void u32pa_be(u32 *val, size_t len)
DESCRIPTION
All of these aim to ensure a value or variable is in expected endianness.
The u32_le() and u32_be() macros will return the value after having read
the given number u as a little endian or big endian value, respectively.
The u32p_le() and u32p_be() macros are similar, only they take a pointer
to an u32 and will convert it into little endian or big endian, respectively.
Finally the u32pa_le() and u32pa_be() macros are similar to the previous
two, only they take an array of u32 of size len and convert every element.
Note that these are macros they may be either no-op or byte swapping functions depending on the endianness of the host.
RETURN VALUE
Only u32_le() and u32_be() have a return value, that of the number u read
as a little or big endian number, respectively.
