sysctl add macros

[Venkata Duvvuru]

The problem with using int or u_int for 1 or 2 byte values is that while printing these 1 or 2 byte values I observed that sysctl module is considering 4 bytes. Hence I see an undesired output. It is actually considering the next two bytes also as the value.

Hi,
I'm unable to figure out how to add an unsigned short or an unsigned char values to a sysctl node.
SYSCTL_ADD_INT, SYSCTL_ADD_UINT, etc., are present but to add a char or a short values I couldn't find any macros.

Could you please let me know how to add them?

FreeBSD does not have any sysctl handlers for 1 or 2 byte values.  FreeBSD code that wants to do this has used int or u_int instead of a smaller type.
