Exception: SystemCallError

Inherits:

StandardError

• Object
• Exception
• StandardError
• SystemCallError

Defined in:

error.c

Class Method Summary

• .===(other) ⇒ Boolean

  Return true if the receiver is a generic SystemCallError, or if the error numbers self and other are the same.

Instance Method Summary

• #errno ⇒ Fixnum

  Return this SystemCallError's error number.

• #new(msg, errno) ⇒ Object constructor

  If errno corresponds to a known system error code, constructs the appropriate Errno class for that error, otherwise constructs a generic SystemCallError object.

Constructor Details

#new(msg, errno) ⇒ Object

If errno corresponds to a known system error code, constructs the appropriate Errno class for that error, otherwise constructs a generic SystemCallError object. The error number is subsequently available via the errno method.
