Hello Sebastian,

This news group is for the pre-builder compiler, actually. The builder
groups all have cppbuilder in their names.
But this question really is not builder-specific...

From the on-line help's calling convention options:

C

(Command-line switch: -pc, -p-)

This option tells the compiler to generate a C calling sequence for function
calls (generate underbars, case sensitive, push parameters right to left).
This is the same as declaring all subroutines and functions with the _
_cdecl keyword. Functions declared using the C calling convention can take a
variable parameter list (the number of parameters does not need to be
fixed).

Standard Call

(Command-line switch: -ps)

This option tells the compiler to generate a Stdcall calling sequence for
function calls (does not generate underscores, preserve case, called
function pops the stack, and pushes parameters right to left). This is the
same as declaring all subroutines and functions with the _ _stdcall keyword.
Functions must pass the correct number and type of arguments.


They are mutually exclusive, use one or the other. The main differences are
the "C" convention adds a leading underscore, preserves the case of the
name, and allows a variable number of arguments.

Regards,
Bruce
