On a project we were recently working on, some legacy
C code was producing a
(void*) voidBuffer accompanied by its size.
The rest of the project was in
C++ and we needed to convert the
(void*) voidBuffer to a
std::vector<unsigned char> vector.
To do so, we used the following code:
//First cast the (void *) voidBuffer to an (unsigned char *) to implicitly get the element size (1 Byte each) const unsigned char *charBuffer = (unsigned char *) voidBuffer; //Then we create the vector (named vectorBuffer) by copying the contents of charBuffer to the vector std::vector<unsigned char> vectorBuffer(charBuffer, charBuffer + length);
