MdeModulePkg: Refine the services comments in EFI_PRINT2_PROTOCOL
For the following 8 services in EFI_PRINT2_PROTOCOL: UNICODE_BS_PRINT UNICODE_S_PRINT UNICODE_BS_PRINT_ASCII_FORMAT UNICODE_S_PRINT_ASCII_FORMAT ASCII_BS_PRINT ASCII_S_PRINT ASCII_BS_PRINT_UNICODE_FORMAT ASCII_S_PRINT_UNICODE_FORMAT 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 services.

This function is similar as snprintf_s defined in C11.
|
||||
|
||||
If BufferSize > 0 and StartOfBuffer is NULL, then ASSERT().
|
||||
If BufferSize > 0 and FormatString is NULL, then ASSERT().
|
||||
If BufferSize > 0 and FormatString is not aligned on a 16-bit boundary, then ASSERT().
|
||||
Produces a Null-terminated ASCII string in the output buffer specified by StartOfBuffer
|
||||
and BufferSize.
|
||||
The ASCII string is produced by parsing the format string specified by FormatString.
|
||||
Arguments are pulled from the variable argument list based on the contents of the
|
||||
format string.
|
||||
The number of ASCII characters in the produced output buffer is returned not including
|
||||
the Null-terminator.
|
||||
|
||||
If FormatString is not aligned on a 16-bit boundary, then ASSERT().
|
||||
|
||||
If BufferSize > 0 and StartOfBuffer is NULL, then ASSERT(). Also, the output buffer is
|
||||
unmodified and 0 is returned.
|
||||
If BufferSize > 0 and FormatString is NULL, then ASSERT(). Also, the output buffer is
|
||||
unmodified and 0 is returned.
|
||||
If PcdMaximumAsciiStringLength is not zero, and BufferSize >
|
||||
(PcdMaximumAsciiStringLength * sizeof (CHAR8)), then ASSERT(). Also, the output buffer
|
||||
is unmodified and 0 is returned.
|
||||
If PcdMaximumUnicodeStringLength is not zero, and FormatString contains more than
|
||||
PcdMaximumUnicodeStringLength Unicode characters not including the Null-terminator, then ASSERT().
|
||||
If PcdMaximumAsciiStringLength is not zero, and produced Null-terminated ASCII string
|
||||
contains more than PcdMaximumAsciiStringLength ASCII characters not including the
|
||||
Null-terminator, then ASSERT().
|
||||
PcdMaximumUnicodeStringLength Unicode characters not including the Null-terminator, then
|
||||
ASSERT(). Also, the output buffer is unmodified and 0 is returned.
|
||||
|
||||
If BufferSize is 0, then no output buffer is produced and 0 is returned.
|
||||
|
||||
@param StartOfBuffer A pointer to the output buffer for the produced Null-terminated
|
||||
ASCII string.
|
||||
@param BufferSize The size, in bytes, of the output buffer specified by StartOfBuffer.
|
||||
@param FormatString Null-terminated Unicode format string.
|
||||
@param FormatString A Null-terminated Unicode format string.
|
||||
@param ... Variable argument list whose contents are accessed based on the
|
||||
format string specified by FormatString.
