Gives you the first four bytes of the file's contents. This signature is often times called a magic value.
Syntax
uint32_t truxton_message_get_signature( uint64_t message_handle );
Parameters
message_handle
The handle to a message created by the truxton_message_create call.
Return value
The first four bytes of the file's contents. If the file length is less than four, this value will be padded with zeroes.
Sample
void dump_signature(uint64_t message)
{
uint32_t signature = truxton_message_get_signature( message );
printf( "Signature is %08" PRIX32 "\n", signature );
}
