Syntax of Structured Exceptions (C++)

Go Up to Structured Exceptions Under Win32 (C++)

In a C program, the ANSI-compatible keywords used to implement structured exceptions are:

• __except,
• __finally
• __try

Note: The __try keyword can only appear in C programs. If you want to write portable code, do not use structured exception handling in your C++ programs.

try-except exception handling syntax

For try-except exception handling, the syntax is as follows:

try-block:

__try compound-statement (in a C module)
try compound-statement (in a C++module)

 handler:

__except (expression) compound-statement

try-finally termination syntax

For try-finally termination, the syntax is as follows:

try-block:

__try compound-statement (in a C module)
try compound-statement (in a C++module)

 termination:

__finally compound-statement
