For the following 12 APIs in MdePkg/BasePrintLib: UnicodeVSPrint UnicodeBSPrint UnicodeSPrint UnicodeVSPrintAsciiFormat UnicodeBSPrintAsciiFormat UnicodeSPrintAsciiFormat AsciiVSPrint AsciiBSPrint AsciiSPrint AsciiVSPrintUnicodeFormat AsciiBSPrintUnicodeFormat AsciiSPrintUnicodeFormat They will ASSERT when: 1) The input parameter 'StartOfBuffer' is NULL if 'BufferSize' indicates at least 1 Ascii/Unicode character can be held. 2) The input parameter 'FormatString' is NULL if 'BufferSize' indicates at least 1 Ascii/Unicode character can be held. 3) The input parameter 'FormatString' contains more than PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters. 4) The produced string contains more than PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters. This commits removes the ASSERT case 4) and add the following new ASSERT case: 4) The input parameter 'BufferSize' is greater than (PcdMaximumAsciiStringLength * sizeof (CHAR8)) for Ascii format string or (PcdMaximumUnicodeStringLength * sizeof (CHAR16) + 1) for Unicode format string. And for those ASSERT cases, 0 will be returned by those 12 APIs. For the following 2 APIs in MdePkg/BasePrintLib: SPrintLength SPrintLengthAsciiFormat They will ASSERT when: 1) The input parameter 'FormatString' is NULL. 2) The input parameter 'FormatString' contains more than PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters. And for those ASSERT cases, 0 will be returned by those 2 APIs.
