Hi,

Try below:

#if defined(BIG_ENDIAN)
#define htons(A) (A)
#define htonl(A) (A)
#define ntohs(A) (A)
#define ntohl(A) (A)
#elif defined(LITTLE_ENDIAN)
#define htons(A) ((((A) & 0xFF00) >> 8) | \
(((A) & 0x00FF) << 8))
#define htonl(A) ((((A) & 0xFF000000) >> 24) | \
        (((A) & 0x00FF0000) >> 8) | \
        (((A) & 0x0000FF00) << 8) | \
(((A) & 0x000000FF) << 24))



or you can refer to linux net source code or ucip on sourceforg.net.

Good Luck
