## Function Documentation

## ◆ osmo_load32be()

static uint32_t osmo_load32be | ( | const void * | p | ) |
| inline static

load unaligned 32-bit integer (big-endian encoding)

References osmo_load32be_ext().

## ◆ osmo_load32be_ext()

static uint32_t osmo_load32be_ext | ( | const void * | p,
|  | uint8_t | n
| ) |  |
| inline static

load unaligned n-byte integer (big-endian encoding) into uint32_t, into the MOST significant octets.

WARNING: for n < sizeof(uint32_t), the result is not returned in the least significant octets, as one might expect. To always return the same value as fed to osmo_store32be_ext() before, use osmo_load32be_ext_2().

Parameters

  [in] | p | Buffer where integer is stored
  [in] | n | Number of bytes stored in p

Returns
  32 bit unsigned integer
