A descriptor , also commonly called a file handle is an object that a program uses to read or write an open file, or open network socket, or a variety of other devices. ... The operating system enforces a limit on the number of descriptors that a program can have open at a time. ... One is a kernel limitation, depending on your operating system you will either be able to tune the number of descriptors available to higher numbers (this is frequently called FD_SETSIZE ). ...
