DESCRIPTION

The system modules store the error code of failed system calls in errno. The value of errno is not changed when non-erroneous calls are made.

The associated error messages are stored in message and the short names (identical to the names of the constants) may be found in name. Empty strings are stored in message and name for unused error numbers.

FILES

The error codes have been extracted from /usr/include/sys/errno.h.

BUGS

The synopsis above is a snapshot of Solaris 2.5.1 and may be different on your system.
