I would like to know if the following construct was ever considered by
the C++ and if it was, why it was rejected.
try
{
// some code that could generate an exception...
}
catch ( // some expected exception type )
{
// handler code
}
finally
{
// code that would be guaranteed to execute no matter how the
// function was exited.
}
This can be written quite easily as I see it with C++, though the
structure is a little awkward.
Basically you just need to write a destructor. The code ordering is a
little less pleasant
Say,
func( ... )
{
class finally{
public:
~finally()
{
// code that would be guaranteed to execute no matter how the
// function was exited.
} finally;
try
{
// some code that could generate an exception...
}
catch ( // some expected exception type )
{
// handler code
}
}
