The standard header files shipped with the Microsoft C compilers do
not contain prototypes for the functions C_INIT() and C_TERM(). These
functions are called only in specific situations when writing DLLs;
therefore, they were specifically left out of the header files.
When writing DLLs with Microsoft C, you can write your own
initialization and termination routines to override the default
initialization and termination. (This procedure is documented on pages
395-397 of the "Advanced Programming Techniques" manual shipped with C
6.00.) To do this, you must make a call in your code to the functions
C_INIT() and C_TERM(), respectively.
Because these functions are not prototyped anywhere, you must include
your own prototypes to guarantee the correct calling conventions for
these functions and to avoid unresolved external errors when linking.
The correct prototypes are as follows:
void _far _pascal C_INIT( void );
void _far _pascal C_TERM( void );
Note that _far and _pascal must be specified without the underscore if
you are using C version 5.10.
