Truxton etl set expander identifier

This is an arbitrary value you choose to uniquely identify your ETL process. This should be a fixed value that you never change. It will be written to the [Expander] column of the [ExpandedFile] table.

Syntax

void etl_set_expander_identifier( uint64_t handle, uint64_t application_id );

Parameters

etl_handle

The handle created by the truxton_etl_create call.

application_id

A unique (usually random) value that permanently identifies your ETL process.

Sample

#include <TruxtonCAPI.h>

void main( void )
{
    char file_id[ 65 ];

    uint64_t message = 0;
    uint64_t app = truxton_etl_create();

    truxton_etl_set_application_name( app, "Sample C ETL" );
    truxton_etl_set_stage_number( app, 42 );
    truxton_etl_set_queue_name( app, "SampleC" );
    truxton_etl_set_expander_identifier( app, 0x05FC0BF6A57726A0 );

    // Pause here until we get a message from the "SampleC" message queue
    message = truxton_etl_get_message( app );

    while( message != 0 )
    {
        // Do something with the message

        memset( file_id, 0x00, sizeof( file_id ) );
        truxton_message_get_file_id( message, file_id, sizeof( file_id ) );

        printf( "Received file id %s\n", file_id );

        truxton_message_destroy( message );

        // Pause here until we get another message from the "SampleC" message queue
        message = truxton_etl_get_message( app );
    }

    truxton_etl_destroy( app );
}
