This retrieves the load configuration used to load the data.
This corresponds to the LoadConfigurationID column of the Media table.
It should be a value from the ID column of the LoadConfiguration table.
A load configuration is the mapping of file types to the message queues that will process it.
Syntax
uint64_t truxton_media_get_load_configuration_id( uint64_t media_handle );
Parameters
media_handle
The handle created by the truxton_media_open_id or truxton_media_create call.
Return value
The identifier for the load configuration.
Sample
void dump_route(uint64_t media)
{
uint64_t id = truxton_media_get_load_configuration_id( media );
printf( "The media is using configuration %" PRIu64 " to process the data\n", id );
}
The PRIu64 in the sample code above is a standard way of formatting a 64-bit unsigned integer in C.
Over the years, different compilers on different operating systems used different format specifiers for things, these PRI macros, along with some tricky string concatenation the compilers perform for you, allow you to maintain a single code base without a bunch of macro magic.
