This retrieves a file from Truxton by its GUID.
Syntax
uint64_t truxton_file_open_id( uint64_t truxton_handle, char const * guid_string );
Parameters
truxton_handle
The handle created by the truxton_create call.
guid_string
The string representation of the identifier of the file to get in Truxton.
This corresponds to the [ID] column of the [File] table.
The file identifier is not random.
Return value
A handle to a read-only file in Truxton.
Sample
int check_it( uint64_t truxton )
{
uint64_t file = truxton_file_open_id( truxton, "5ed3aeb7-3da4-5f5c-8c8f-af5200000000" );
if ( file == 0 )
{
return( 0 );
}
truxton_file_close( file );
truxton_file_free( file );
return( 1 )
}
