If someone can help me, I would like to write equal functions in C language. Thanks.

Buffer without overlap is easy.
- take the length of the signal
- do an integer division by the buffer length to get the number of buffers
- take the signal length modula the buffer length
- if the modula is non-zero add one to the number of buffers
- allocate a chunk of memory that is (number of buffers times buffer length) long.
- memcpy the signal into the buffer
- if the modulo of the signal length and the buffer was non-zero then initialize the rest of the buffer to zero
