Of course it allows it, but it is up to the language in which the call is made to decide what is allowed. C++ cannot force a C compiler to allow linkage to a C++ implemented function. However, as long as such things as size and alignment are compatible, C++ can require that a C++ compiler supports calling a function written in C. This is very much language law at the extreme:) Francis Glassborow ACCU 64 Southfield Rd Oxford OX4 1PA +44(0)1865 246490 All opinions are mine and do not represent those of any organisation --- [ comp.std.c++ is moderated.
