endtry — Ends a block where exceptions are handled.
endtry( : : : )
With the help of the operators try, catch, endtry, and throw it is possible to implement a dynamic exception handling in HDevelop, which is comparable to the exception handling in C++ and C#. The basic concepts of the exception handling in HDevelop are described at the operators try, throw, and dev_set_check as well as in the “HDevelop User's Guide”.
The operator endtry closes the exception handling block that was opened with the operators try and catch.
The export of the operators try, catch, endtry, and throw is not supported for the languages C and VisualBasic 6.0, but only for the languages C++, C# and VisualBasic/.NET. Only the latter support throwing exceptions across procedure.
endtry always returns 2 (H_MSG_TRUE).
