Truxton etl set description

This is used to build the command line arguments for the process. Truxton will automatically parse the command line for you but this allows you to programmatically force command line options.

Syntax

void truxton_etl_set_description(uint64_t etl_handle, char const * description)

Parameters

etl_handle

The handle created by the truxton_etl_create call.

description

A human readable string that describes what your ETL process is supposed to do.

Sample

#include <TruxtonCAPI.h>

void main( void )
{
    char file_id[ 65 ];
    char description[ 128 ];

    int exit_loop = 0;

    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_description( app, "A sample of how to write an ETL");
    truxton_etl_get_description( app, description, sizeof(description));

    while( exit_loop == 0 )
    {
        message = truxton_etl_get_message( app );

        if ( 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 );
        }
        else
        {
            exit_loop = 1;
        }
    }
}
