VOID* EFIAPI LibPatchPcdSetPtr ( OUT VOID *  PatchVariable,
IN UINTN  MaximumDatumSize,
IN OUT UINTN *  SizeOfBuffer,
IN CONST VOID *  Buffer 
)

Sets a value of a patchable PCD entry that is type pointer.

Sets the PCD entry specified by PatchVariable to the value specified by Buffer and SizeOfBuffer. Buffer is returned. If SizeOfBuffer is greater than MaximumDatumSize, then set SizeOfBuffer to MaximumDatumSize and return NULL to indicate that the set operation was not actually performed. If SizeOfBuffer is set to MAX_ADDRESS, then SizeOfBuffer must be set to MaximumDatumSize and NULL must be returned.

If PatchVariable is NULL, then ASSERT(). If SizeOfBuffer is NULL, then ASSERT(). If SizeOfBuffer > 0 and Buffer is NULL, then ASSERT().

Parameters:
[out] PatchVariable A pointer to the global variable in a module that is the target of the set operation.
[in] MaximumDatumSize The maximum size allowed for the PCD entry specified by PatchVariable.
[in,out] SizeOfBuffer A pointer to the size, in bytes, of Buffer.
[in] Buffer A pointer to the buffer to used to set the target variable.
Returns:
Return the pointer to the buffer that was set.

IN CONST VOID *  Buffer 
)

This function provides a means by which to set a value for a given PCD token.

Sets a buffer for the token specified by TokenNumber to the value specified by Buffer and SizeOfBuffer. Buffer is returned. If SizeOfBuffer is greater than the maximum size support by TokenNumber, then set SizeOfBuffer to the maximum size supported by TokenNumber and return NULL to indicate that the set operation was not actually performed.

If SizeOfBuffer is set to MAX_ADDRESS, then SizeOfBuffer must be set to the maximum size supported by TokenName and NULL must be returned.

IN OUT UINTN *  SizeOfBuffer,
IN CONST VOID *  Buffer 
)

This function provides a means by which to set a value for a given PCD token.

Sets a buffer for the token specified by TokenNumber to the value specified by Buffer and SizeOfBuffer. If SizeOfBuffer is greater than the maximum size support by TokenNumber, then set SizeOfBuffer to the maximum size supported by TokenNumber and return EFI_INVALID_PARAMETER to indicate that the set operation was not actually performed.

If SizeOfBuffer is set to MAX_ADDRESS, then SizeOfBuffer must be set to the maximum size supported by TokenName and EFI_INVALID_PARAMETER must be returned.

If SizeOfBuffer is NULL, then ASSERT(). If SizeOfBuffer > 0 and Buffer is NULL, then ASSERT().

Parameters:
[in] TokenNumber The PCD token number to set a current value for.
[in,out] SizeOfBuffer The size, in bytes, of Buffer.
[in] Buffer A pointer to the buffer to set.
Returns:
The status of the set operation.
