David,
You can set that PCD value in the DSC file used to build your app.
The UefiLib also has a function called CatSPrint() which may be a better match
for what you want:
/**
Appends a formatted Unicode string to a Null-terminated Unicode string
This function appends a formatted Unicode string to the Null-terminated
Unicode string specified by String. String is optional and may be NULL.
Storage for the formatted Unicode string returned is allocated using
AllocatePool(). The pointer to the appended string is returned. The caller
is responsible for freeing the returned string.
If String is not NULL and not aligned on a 16-bit boundary, then ASSERT().
If FormatString is NULL, then ASSERT().
If FormatString is not aligned on a 16-bit boundary, then ASSERT().
@param[in] String A Null-terminated Unicode string.
@param[in] FormatString A Null-terminated Unicode format string.
@param[in] ... The variable argument list whose contents are
accessed based on the format string specified by
FormatString.
@retval NULL There was not enough available memory.
@return Null-terminated Unicode string is that is the formatted
string appended to String.

CHAR16 *
EFIAPI
CatSPrint (
IN CHAR16 *String, OPTIONAL
IN CONST CHAR16 *FormatString,
...
)

Subject: [edk2] change value of PcdUefiLibMaxPrintBufferSize
Hi,
How do you change the value of:
## The maxium allowable size of formatted unicode string
gEfiMdePkgTokenSpaceGuid.PcdUefiLibMaxPrintBufferSize|320|UINT32|0x101
Without changing it in the MdePkg.dec file itself. So I could just change it
in my app?
It didn't like SetPcd32(PcdUefiLibMaxPrintBufferSize, 2048); .. maybe missing
include file?
It would be better if the routines just adjusted buffer lengths as needed,
but...
TIA!!
