-Module Name:\r
-\r
- Print.c\r
-\r
-Abstract:\r
-\r
- Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very\r
- simple implemenation of SPrint() and Print() to support debug. \r
-\r
- You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a \r
- time. This makes the implementation very simple.\r
-\r
- VSPrint, Print, SPrint format specification has the follwoing form\r
-\r
- %[flags][width]type\r
-\r
- flags:\r
- '-' - Left justify\r
- '+' - Prefix a sign\r
- ' ' - Prefix a blank\r
- ',' - Place commas in numberss\r
- '0' - Prefix for width with zeros\r
- 'l' - UINT64\r
- 'L' - UINT64\r
-\r
- width:\r
- '*' - Get width from a UINTN argumnet from the argument list\r
- Decimal number that represents width of print\r
-\r
- type:\r
- 'X' - argument is a UINTN hex number, prefix '0'\r
- 'x' - argument is a hex number\r
- 'd' - argument is a decimal number\r
- 'a' - argument is an ascii string \r
- 'S','s' - argument is an Unicode string\r
- 'g' - argument is a pointer to an EFI_GUID\r
- 't' - argument is a pointer to an EFI_TIME structure\r
- 'c' - argument is an ascii character\r
- 'r' - argument is EFI_STATUS\r
- '%' - Print a %\r
