cb_link_stats_struct, x25_query_data, or x25_stats Structure for X.25

cb_links_stats_struct Structure

Used by the x25_link_statistics subroutine to pass statistics about an X.25 port.

#define X25FLG_NO_OF_VCS          0x00000008
#define X25FLG_LINK_STATS         0x00000020
struct cb_link_stats_struct
  unsigned long flags;
  unsigned int no_of_vcs;
  struct x25_query_data x25_stats;
} ;


X25_FLG_NO_OF_VCS Indicates that the no_of_vcs field is used.
X25_FLG_LINK_STATS Indicates that the x25_stats structure is being used.


flags Notification to the API that the associated field has been used
no_of_vcs Number of virtual circuits currently in use for the X.25 port specified
x25_stats Pointer to an x25_query_data structure containing CIO and X.25 statistics

x25_query_data Structure

The x25_query_data structure is returned from the CIO_QUERY ioctl operation. It includes two structures: the cio_stats structure containing standard statistics values found in the sys/comio.h file, and the x25_stats structure containing specific X.25 statistics.

struct x25_query_data
  struct cio_stats cc;
  struct x25_stats ds;

x25_stats Structure

The x25_stats structure contains specific X.25 statistics.

Note: Flags are not used with this structure.
