sdaiInsertAfter

valueType argument to specify what type of data caller wants to put Table 1 shows type of buffer the caller should provide depending on the valueType for sdaiInsertAfter, and it works similarly for all put-functions. Note: with SDAI API it is impossible to check buffer type at compilation or execution time and this is responsibility of a caller to ensure that requested valueType is matching with the value argument, a mismatch will lead to unpredictable results.

Table 1 � Required value buffer depending on valueType (on the example of sdaiInsertAfter but valid for all put-functions)

TCHAR is �char� or �wchar_t� depending on setStringUnicode. (Non-standard behavior) sdaiLOGICAL behaves differently from ISO 10303-24-2001: it expects char* while standard declares int_t. (Non-standard extension) sdiADB in C++ has an option to work without sdaiCreateEmptyADB and sdaiDeleteADB as shown in the table.
