Linux below errno.h file error number description

In centos6.2, it is divided into two files, one in/usr/include/asm-generic/errno-base.h, the other in/usr/include/asm-generic/errno.h

The contents of the/usr/include/asm-generic/errno-base.h file are as follows:

 <span style= "FONT-SIZE:12PX;"  > #define EPERM 1/* Operation not permitted/#define ENOENT 2/* No such file or directory */#define ESRCH 3/* No such process/#define EINTR 4/* Interrupted system call/#define EIO 5 * I/O error/#define ENXIO 6/N O such device or address/#define E2BIG 7/* Argument list too long */#define ENOEXEC 8/* Exec format error */#de Fine EBADF 9/* Bad file number/#define ECHILD/* No Child processes * * #define EAGAIN/* Try again/* #defin e Enomem/out of memory * * * #define EACCES/* Permission denied/#define EFAULT/* Bad address/#define E NOTBLK/* block device required/#define EBUSY/* Device or resource busy/#define EEXIST/* File exists *  /#define EXDEV/* cross-device link/#define ENODEV/* No such device * * #define ENOTDIR/Not Directory
