extern uint16_t  inet_checksum (const uint8_t *addr, size_t len)

inet_checksum

#include <checksum.h>


Checksum computation for Internet Protocol family headers.

Parameters:

addrthe address with the data.
lenthe length of the data.

Returns: the calculated checksum (in network order).

extern uint16_t  inet_checksum_add (uint16_t sum1, uint16_t sum2)

inet_checksum_add

#include <checksum.h>


Add two previously computed checksums for Internet Protocol family header.

Parameters:

sum1the first sum to add.
sum2the second sum to add.

Returns: the sum of the two checksums.

TODO: temporary, all names are listed in "_xorp_module_name[][]" in proto_unit.cc.

Parameters:

familythe address family (e.g., AF_INET or AF_INET6 for IPv4 and IPv6 respectively).
module_idthe module ID (xorp_module_id).

Returns: C-style string with the module name.

xorp_module_id  xorp_module_name2id (const char *module_name)
