Question:
Conventional high-level programming languages rely on sequential semantics for their operation. In particular, when programmers write a code segment such as
.
read (io-port, &buffer, length);
x = f (buffer[i]);
.
they expect the assignment statement will not be executed until the read statement has retrieved input data and written it into memory at address buffer. Write a pseudo code description of how these semantics could be implemented with a read ( ) library routine and a corresponding program to use the routine.
