SUMMARY

The Simple MAPI C function, MAPIAddress, does not dynamically allocate memory, as suggested in the MAPI Software Developer's Kit (SDK) online documentation.

MORE INFORMATION

The MAPI SDK online documentation states the following for the lppNewRecips parameter of the MAPIAddress function:

lppNewRecips
Output parameter pointing to an array of MapiRecipDesc structures containing the final list of recipients. This array is allocated by MAPIAddress...

This description implies that the MAPIAddress function allocates an array for the MapiRecipDesc structures. This is not accurate. In order to use this function properly, you must allocate memory for the array with a MALLOC statement in your code. If you do not do this, you may receive an exception error in Kernel32.dll and/or a MAPI_E_FAILURE error when using the MAPIAddress function.
