2. Textbook, P. 151 -> question 13. (question 13: Describe a new read function, xRead(),along with other functions that could enable one to write programs in a high-levellanguage such that the application can continue processing after the xRead() call, but canblock itself before using data in the process of being read) In this question, you just need to:

a. Explain the basic idea about how to implement xRead().

b. Use a high-level language pseudocode (for example, C or C++ style pseudocodein the textbook) to develop an application, which can continue processing afterthe xRead() call, but can block itself before using data in the process of being read.
