Summary of Library Header Files

The header errnoh declares one function and several object-like macros that are used by

several library functions to report errors. The function declared is errno, and returns a

value of type int. The ISO/ANSI C standard requires that the C run-time library return

only positive integral values to errno. Table 2-1 lists the macros and their symbolic

meanings.
