-Module Name:
-
- Print.c
-
-Abstract:
-
- Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very
- simple implemenation of SPrint() and Print() to support debug.
-
- You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a
- time. This makes the implementation very simple.
-
- VSPrint, Print, SPrint format specification has the follwoing form
-
- %type
-
- type:
- 'S','s' - argument is an Unicode string
- 'c' - argument is an ascii character
- '%' - Print a %
