The arguments are: vp The vnode to get information about. name The type of information to return. retval The place to return the information. The value of name specifies what should be returned: _PC_LINK_MAX The maximum number of links to a file. _PC_NAME_MAX The maximum number of bytes in a file name. _PC_PATH_MAX The maximum number of bytes in a pathname. _PC_PIPE_BUF The maximum number of bytes which will be written atomically to a pipe. _PC_CHOWN_RESTRICTED Return 1 if appropriate privileges are required for the chown(2) system call, otherwise 0. _PC_NO_TRUNC Return 1 if file names longer than KERN_NAME_MAX are truncated.
If name is recognized, *retval is set to the specified value and zero is returned, otherwise EINVAL is returned.
