Function setBlob


#include <Source/Falcor/Core/API/Buffer.h>

bool setBlob(const void *pData, size_t offset, size_t size)


Update the buffer's data


[ in ] pData - Pointer to the source data.

[ in ] offset - Byte offset into the destination buffer, indicating where to start copy into.

[ in ] size - Number of bytes to copy. If offset and size will cause an out-of-bound access to the buffer, an error will be logged and the update will fail.
