NOF API Verbs
QUERY_DLC_TRACE
overlay_size
The size of the returned
dlc_trace_data
structure, and therefore the offset to the start of the next entry in the
data buffer.
When your application needs to go through the returned buffer to find each
dlc_trace_data structure in turn, it
must use this value to move to the correct offset for the next data structure, and must not use the C
sizeof()
operator. This is because the size of the returned overlay may increase in future releases of SNAplus2; using
the returned overlay size ensures that your application will continue to work with future releases.
dlc_trace_filter.resource_type
The type of resource being traced. This can take one of the following values:
ALL_RESOURCES
The entry specifies tracing options for all resources.
AP_DLC
The entry specifies tracing options for the DLC named in
resource_name, and for all ports and LSs that
use this DLC.
AP_PORT
The entry specifies tracing options for the port named in resource_name, and for all LSs that use this
port.
AP_LS
The entry specifies tracing options for the LS named in resource_name (or for a particular LFSID on
this LS).
AP_RTP_RESOURCE_TYPE
The entry specifies tracing options for the RTP connection named in resource_name.
AP_PORT_DEFINED_LS
The entry specifies tracing options for the port named in resource_name, and for all defined LSs (but
not implicit LSs) that use this port.
AP_PORT_IMPLICIT_LS
The entry specifies tracing options for the port named in resource_name, and for all implicit LSs (but
not defined LSs) that use this port.
dlc_trace_filter.resource_name
The name of the DLC, port, or LS being traced.
dlc_trace_filter.lfsid
The Local Form Session Identifier for a session on the specified LS. This is only valid for resource_type
AP_LS, and indicates that only messages on this session are to be traced. The structure contains the following
three values, which are returned in the SESSION_STATS section of a QUERY_SESSION verb:
dlc_trace_filter.lfsid.uu.s.sidh
Session ID high byte.
dlc_trace_filter.lfsid.uu.s.sidl
Session ID low byte.
dlc_trace_filter.lfsid.odai
Origin Destination Assignor Indicator.
dlc_trace_filter.message_type
The type of messages being traced for the specified resource or session. This parameter is set to
AP_TRACE_ALL
to trace all messages, or to one or more of the following values (combined using a logical OR):
