Truxton artifact get length

This tells you the number of raw bytes that make up the artifact. This may not match the length of the string representation of the artifact value. For example, the artifact may be three emoticons but the length of the raw bytes could be 12 if the raw bytes are UTF-8 encoded. This information comes from the [Length] column of the [Entity] table in the database.

Syntax

uint64_t truxton_artifact_get_length( uint64_t artifact_handle );

Parameters

artifact_handle

The artifact instance. This handle comes from calling truxton_artifact_create().

Return value

The number of bytes in the raw artifact.

Sample

void create_artifact( void )
{
   uint64_t truxton = truxton_create();

   uint64_t artifact = truxton_artifact_create( truxton );

   truxton_artifact_set_name( artifact, "Ducky Momo Server" );
   truxton_artifact_set_length( artifact, 42 );
   truxton_artifact_save( artifact );
   truxton_artifact_tag( artifact, "Too Young", "Yes, yes I am", 1 );

   uint64_t length = truxton_artifact_get_length( artifact );

   printf( "Artifact raw length is%" PRIu64 "\n", length );

   truxton_artifact_destroy( artifact );
   truxton_destroy( truxton );
}

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.
