在向社区贡献代码过程中，Code style 十分重要，如果code style有问题，大概率不能通过code review.本文以 edk2 中一段程序为例会大致说明，C 语言在UEFI中大致遵循的规则，

UINT64        gAllZero = 0;

/**
  The Entry Point for PCI Bus module. The user code starts with this function.

  Installs driver module protocols and. Creates virtual device handles for ConIn,
  ConOut, and StdErr. Installs Simple Text In protocol, Simple Text In Ex protocol,
  Simple Pointer protocol, Absolute Pointer protocol on those virtual handlers.
  Installs Graphics Output protocol and/or UGA Draw protocol if needed.

  @param[in] ImageHandle    The firmware allocated handle for the EFI image.
  @param[in] SystemTable    A pointer to the EFI System Table.

  @retval EFI_SUCCESS       The entry point is executed successfully.
  @retval other             Some error occurred when executing this entry point.

**/
EFI_STATUS
EFIAPI
PciBusEntryPoint (
  IN EFI_HANDLE        ImageHandle,
  IN EFI_SYSTEM_TABLE  *SystemTable
  )
{
   
  EFI_STATUS  Status;
  EFI_HANDLE  Handle;

  //
  // Initializes PCI devices pool
