The number contained at the specified position in the buffer, or nil if the buffer is undefined at the given position.
This function deletes a single character from a raw memory buffer. The buffer length does not change as a result of this function. A zero character is placed at the empty position at the end of the buffer, then the buffer is collapsed.
