Golang Opcode Examples

Example #1

File: parser.go Project: nmuth/synacor-go

// Read a register address from the file input.
func NextOpcode(fileInput io.Reader) (result opcode.Opcode, err error) {
	num, err := NextCodepoint(fileInput)

	if err == nil {
		result = opcode.Opcode(num)
	}

	return result, err
}
