NAME

     error_temp - identify soft syscall error codes

SYNTAX

     #include <error.h>

     int error_temp(e);

     int e;

DESCRIPTION

     error_temp returns 1 if syscall  error  code  e  is  a  soft
     error, 0 if it is a hard error.  Normally e is errno.

     A hard error is persistent:  file not found, read-only  file
     system, symbolic link loop, etc.

     A soft error is usually transient:  out of  memory,  out  of
     disk  space,  I/O  error,  disk  quota  exceeded, connection
     refused, host unreachable, etc.
