WWAN_MODEM_LOGGING_CONFIG structure (wwan.h)

  • Article

The WWAN_MODEM_LOGGING_CONFIG structure describes the current modem logging configuration for a modem.

Syntax

typedef struct _WWAN_MODEM_LOGGING_CONFIG {
  ULONG                           Version;
  ULONG                           MaxSegmentSize;
  ULONG                           MaxFlushTime;
  WWAN_MODEM_LOGGING_LEVEL_CONFIG LevelConfig;
} WWAN_MODEM_LOGGING_CONFIG, *PWWAN_MODEM_LOGGING_CONFIG;

Members

Version

The version number of the structure that follows. In Windows 10, version 1903, this version must be set to 1.

MaxSegmentSize

The segment size, in kilobytes (KB), for each fragment sent by the modem. If the maximum fragment size supported by the modem for Device Service Commands exceeds the value set, then this value is set to the maximum supported segment size.

MaxFlushTime

The time, in milliseconds, indicating the maximum time the modem waits before sending a log fragment. If the logs collected don't reach MaxSegmentSize within the MaxFlushTime duration since the last log fragment was sent, then a log fragment is sent regardless of its size. If there is no logging data, then no notification is sent. If the device cannot handle smaller flush times, then the device returns the time that it can handle in the response. The response to an OID_WWAN_MODEM_LOGGING_CONFIG Query or Set request contains the currently configured MaxFlushTime.

LevelConfig

A WWAN_MODEM_LOGGING_LEVEL_CONFIG value that configures the level for which logs are collected. The response to an OID_WWAN_MODEM_LOGGING_CONFIG Query or Set request contains the currently configured LevelConfig.

Remarks

This structure is used in the NDIS_WWAN_MODEM_LOGGING_CONFIG structure.
