12Module Name:\r

14 SecMain.c\r
15\r
16Abstract:\r
377fc2ae 17 WinNt emulator of SEC phase. It's really a Posix application, but this is\r
18 Ok since all the other modules for NT32 are NOT Posix applications.\r
c9093a06 19\r
377fc2ae 20 This program processes host environment variables and figures out\r
c9093a06 21 what the memory layout will be, how may FD's will be loaded and also\r
22 what the boot mode is.\r
23\r
24 The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r
25 is a list of PPI's produced by the SEC that are availble for usage in PEI.\r
26\r
27 This code produces 128 K of temporary memory for the PEI stack by opening a\r
377fc2ae 28 host file and mapping it directly to memory addresses.\r
c9093a06 29\r
377fc2ae 30 The system.cmd script is used to set host environment variables that drive\r
c9093a06 31 the configuration opitons of the SEC.\r

352Routine Description:
353 Opens and memory maps a file using WinNt services. If BaseAddress is non zero
354 the process will try and allocate the memory starting at BaseAddress.
355
356Arguments:
357 FileName - The name of the file to open and map
358 MapSize - The amount of the file to map in bytes
359 CreationDisposition - The flags to pass to CreateFile(). Use to create new files for
360 memory emulation, and exiting files for firmware volume emulation
361 BaseAddress - The base address of the mapped file in the user address space.
362 If passed in as NULL the a new memory region is used.
363 If passed in as non NULL the request memory region is used for
364 the mapping of the file into the process space.
365 Length - The size of the mapped region in bytes
366

368 EFI_SUCCESS - The file was opened and mapped.
369 EFI_NOT_FOUND - FileName was not found in the current directory
