NAME¶

MSVCRT___RTDynamicCast (MSVCRT.@)

SYNOPSIS¶

void* CDECL MSVCRT___RTDynamicCast
(
void* cppobj,
int unknown,
type_info* src,
type_info* dst,
int do_throw
)

DESCRIPTION¶

Dynamically cast a C++ object to one of its base classes.

PARAMS¶

cppobj [In] Any C++ object to cast. unknown [In] Reserved, set to 0. src [In] type_info object describing cppobj. dst [In] type_info object describing the base class to cast to. do_throw [In] TRUE = throw an exception if the cast fails, FALSE = don't.

RETURNS¶

Success: The address of cppobj, cast to the object described by dst. Failure: NULL, If the object to be cast has no RTTI, or dst is not a valid cast for cppobj. If do_throw is TRUE, a bad_cast exception is thrown and this function does not return.

NOTES¶

This function is usually called by compiler generated code as a result of using one of the C++ dynamic cast statements.

IMPLEMENTATION¶

Not declared in a Wine header. The function is either undocumented, or missing from Wine. Implemented in "dlls/msvcrt/cpp.c". Debug channel "msvcrt".
