16 program should include the header file @file{errno.h} to use this
18 @pindex errno.h
35 variable @code{errno}.  This variable is declared in the header file

41 The variable @code{errno} contains the system error number.  You can
42 change the value of @code{errno}.
44 Since @code{errno} is declared @code{volatile}, it might be changed
47 of @code{errno}, so you generally do not need to worry about this
