Registers a function as a structured exception handler. (32-bit MASM only.)

Syntax

Remarks

identifier must be the ID for a locally defined PROC or EXTRN PROC. A LABEL is not allowed. The .SAFESEH directive requires the /safeseh ml.exe command-line option.

For more information about structured exception handlers, see /SAFESEH.

For example, to register a safe exception handler, create a new MASM file (as follows), assemble with /safeseh, and add it to the linked objects.
