Reviews

"Despite my having developed systems software with Sockets and C for 20+ years, I find myself still needing a book like this one. It covers all the subtleties and gotchas that one encounters when writing distributed applications in C with Sockets."--- Bobby Krupczak, The Krupczak Organization
