请教几个c函数

请问bzero、bcopy、htons、ntohl几个函数有什么作用？

zhanggz

The bcopy subroutine copies the value of the Length parameter in bytes from the string in the Source parameter to the string in the Destination parameter

The bcmp subroutine compares the byte string in the String1 parameter against the byte string of the String2 parameter, returning a zero value if the two strings are identical and a nonzero value otherwise. Both strings are assumed to be Length bytes long.

The bzero subroutine zeroes out the string in the String parameter for the value of the Length parameter in bytes.
