Hi,

i am using some STL containers in a library of mine.
how can i see which exceptions can occur when doing something
with those containers (adding an elemnt for example)

i have looked in the MSDN collection, but class members lists nothing, and
the specific functions also don't mention anything.

am i looking in the wrong place or doi have to find my way through the STL
sources?

kind regards,
Bruno.

Generally anything that might allocate memory might throw
std::bad_alloc.

Generally the exceptions they throw depend on the exceptions that the
held types throw. If you have a vector<MyType> and the MyType copy
constructor throws, then lots of vector's methods may throw that
exception.

There's a good .pdf on library exception safety here:

(or buy the book).
