Probably not. During string marshaling, the pointer returned from CSharp_Test_ReturnString() will be freed "as if" through System.Runtime.InteropServices.Marshal.FreeCoTaskMem(), which is platform-specific. On Windows, this is CoTaskMemFree(). On non-Windows, this is g_free(). Either way, unless g_free() is aliased as free(3), strdup() will not allocate memory from the appropriate heap. Consequently, you should explicitly allocate your memory with the correct memory allocator and strcpy() the value. - Jon _______________________________________________ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
