Examples and Tests:

COND1 demonstrates the use of a condition variable which can cause a process to wait and then resume execution.

• cond1.c, the program.
• cond1.txt, the output file.

DOT_PRODUCT is an extensive example which shows how the dot product of two vectors could be computed.

• dot_product.c, the program.
• dot_product.txt, the output file.

JOIN1 shows how a thread can wait for other threads to finish.

• join1.c, the program.
• join1.txt, the output file.

MUTEX1 shows how a mutex can be used to control the access by different threads to a single data itme.

• mutex1.c, the program.
• mutex1.txt, the output file.

PTHREAD1 is a simple example which shows how threads are created and terminated.

• pthread1.c, the program.
• pthread1.txt, the output file.
