#include <senf/Utils/Exception.hh>
Detailed Description
Exception handling standard UNIX errors (errno).This exception is thrown to signal generic errno failures. Normally the errno value is automatically taken from the errno variable but it may also be specified explicitly:
// Standard usage: Take \c errno from environment throw senf::SystemException("::open()") << " while opening configuration file: " << filename; // You may however explicitly specify the errno value throw senf::SystemException("::open()", ENOFILE) // Or leave the location information empty throw senf::SystemException(ENOFILE); throw senf::SystemException();
From within SENF (and only there because it depends on the SENF_DEBUG symbol), SystemException should be thrown using wrapper macros which add additional information to the exception description:
// Standard usage: Take \c errno from environment SENF_THROW_SYSTEM_EXCEPTION("::open()") << " while opening configuration file: " << filename; // You may however explicitly specify the errno value throw senf::SystemException("::open()", ENOFILE SENF_EXC_DEBUGINFO)
