• GPSERROR_NONE if the command executes successfully

• GPSERROR_INVALID_PARAMETER if a NULL pointer is passed in pglriInfo

• GPSERROR_MEMORY if there is not enough memory available to execute the command

• GPSERROR_INVALID_RECEIVER if the receiver type is not supported

• This function differs from GpsGetRecordCount in that filtering is supported through the input parameter.

• To retrieve the record count between two dates, supply non-zero values for the glrtStart and glrtEnd members of the pglriInfo parameter.

• To retrieve the record count after a certain date, set the glrtStart member of pglriInfo to a non-zero value and the glrtEnd member to zero.

• To retrieve the record count before a certain date, set the glrtStart member of pglriInfo to zero and the glrtEnd member to a non-zero value.

• To retrieve the record count by sequence number, set both the glrtStart and glrtEnd members of pglriInfo to zero values and the ulStart and ulEnd to the start and end sequence numbers respectively.

• To retrieve the count of all records, set both the glrtStart and glrtEnd members of pglriInfo to zero values and the ulStart and ulEnd to GPSLOGGER_ALL_RECORDS.

• This function is only supported on logger type receivers.
