Histogram program using pthreads
WebbPOSIX Threads are commonly known as PThreads. It is an execution model that exists independently from a language and a parallel execution model. It allows a program to control multiple different workflows that overlap in time. Each flow of work is referred to as a thread. Creation and controlling these flows is achieved by making calls to the ...
