# uint32\_unpack\_big(3)

read an unsigned big-endian 32-bit integer

## NAME

uint32\_unpack\_big - read an unsigned big-endian 32-bit integer

## SYNTAX

**#include \<libowfat/uint32.h\>**

uint32 *u*;

void **uint32\_unpack\_big**(const char *s*\[4\],uint32 \**u*);

## DESCRIPTION

uint32 is a 32-bit unsigned integer type, normally either unsigned int or unsigned long.

uint32\_unpack\_big portably reads a uint32 as stored on a big-endian architecture (i.e. in network byte order) from *s* and writes it into *u* in the native byte order.
