/**
Produces a Null-terminated ASCII string in an output buffer based on a Null-terminated
Unicode format string and variable argument list.
This function is similar as snprintf_s defined in C11.
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(). 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 A Null-terminated Unicode format string.
@param ... Variable argument list whose contents are accessed based on the
format string specified by FormatString.
@return The number of ASCII characters in the produced output buffer not including the
Null-terminator.

Converts a decimal value to a Null-terminated ASCII string.
Converts the decimal number specified by Value to a Null-terminated ASCII string

The number of ASCII characters in Buffer is returned not including the Null-terminator.

the conversion is returned.

If Width is 0, PREFIX_ZERO is ignored in Flags.
