◆ osmo_load32be()

static uint32_t osmo_load32be ( const void *  p)
inlinestatic

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

◆ osmo_load32be_ext()

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

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]pBuffer where integer is stored
[in]nNumber of bytes stored in p
Returns
32 bit unsigned integer
