Calling between C and C++

Table 1 describes the types of calls between C and C++ that Language Environment allows:

Table 1. Calls permitted for C to C++ ILC
Direction of call	Static calls	Dynamic calls using DLLs	Fetch/fetchep
C to C++	Yes	Yes	Yes
C++ to C	Yes	Yes	Yes
Note: The `fetch()` function can be used to fetch modules, compiled DLL, or modules containing C++ routines, but exported data will not be available. Any of the C or C++ functions can be compiled with the XPLINK option, with the single restriction that you cannot mix XPLINK and non-XPLINK in the same module (that is, XPLINK and non-XPLINK C or C++ cannot be statically bound together). As of C/C++ for MVS/ESA V3, the compiler provides support for dynamic load libraries (DLLs) which can be used to dynamically access C or C++ functions or data. For more information about DLLs, see z/OS XL C++ Programming Guide.
