Truxton message get signature

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 );
}
