16 | Abstract:\r | |
17 | \r | |
18 | Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very\r | |
c8dd259d | 19 | simple implemenation of SPrint() and Print() to support debug.\r |
878ddf1f | 20 | \r |
c8dd259d | 21 | You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a\r |
878ddf1f | 22 | time. This makes the implementation very simple.\r |
23 | \r | |
24 | VSPrint, Print, SPrint format specification has the follwoing form\r | |
25 | \r | |
26 | %type\r | |
27 | \r | |
28 | type:\r | |
29 | 'S','s' - argument is an Unicode string\r | |
30 | 'c' - argument is an ascii character\r | |
