Macro Definition Documentation

be32toh

#define be32toh

(

big_endian_32bits

)

Value:

((uint32_t)(((((unsigned char*)&(big_endian_32bits))[0]) << 24) + \
              ((((unsigned char*)&(big_endian_32bits))[1]) << 16) + \
              ((((unsigned char*)&(big_endian_32bits))[2]) << 8) +  \
              (((unsigned char*)&(big_endian_32bits))[3])))

Transform big endian uint32_t to host uint32_t.

htobe32

#define htobe32

(

host_32bits

)

Value:

(uint32_t)(((((uint32_t)(host_32bits)) & 0xFF) << 24) |    \
             ((((uint32_t)(host_32bits)) & 0xFF00) << 8) |   \
             ((((uint32_t)(host_32bits)) & 0xFF0000) >> 8) | \
             ((((uint32_t)(host_32bits)) & 0xFF000000) >> 24))

Transform host uint32_t to big endian uint32_t.
