Annotations for Functions in __try Statements

  • Artigo

Certain functions must be called from inside a structured exception handling __try statement; others are prohibited from being called from inside a __try statement.

Use the __drv_inTry and __drv_notInTry annotations to check for proper usage within a function.

  • __drv_inTry
    The __drv_inTry annotation specifies that the function must be called from inside a __try statement.

  • __drv_notInTry
    The __drv_notInTry annotation specifies that the function must not be called from inside a __try statement.

A typical use for the __drv_inTry annotation would be within the ProbeForRead and ProbeForWrite functions, in which failed attempts to access memory are caught by a __try statement.
