Declares the public Csound application programming interface (API).
Cscore
Beginning with Csound 5, all of the Cscore functions described in the manual are now part of the Csound API, and they can be called from a program that calls the Csound library.
All of the CScore functions are renamed in the Csound API. For example, createv() is now cscoreCreateEvent(), and lcopy() is now cscoreListCopy(). In addition, each function takes an additional first parameter that is a pointer to a CSOUND instance. You can find the details in the header file, cscore.h, which may be included with your Csound distribution, or if not, can be found in Csound CVS `on SourceForge.
Before you can use any of the Cscore API functions, you must create a CSOUND instance and initialize Cscore by calling csoundInitializeCscore() – see csound.h for an explanation. An example main program that does all of this Top/cscormai.c. You should add a function called cscore() with your own score-processing code. An example that does nothing except write the score back out unchanged can be found in the file Top/cscore_internal.c.
To create your own standalone Cscore program, you must compile cscormai.c (or your own main program) and the file containing your cscore() function, and link them with the Csound API library.

Hosts using the Csound API must #include <csound.h>, and link with the Csound API library. Plugin libraries should #include <csdl.h> to get access to the API function pointers in the CSOUND structure, and do not need to link with the Csound API library. Only one of csound.h and csdl.h may be included by a compilation unit.
Hosts must first create an instance of Csound using the csoundCreate API function. When hosts are finished using Csound, they must destroy the instance of csound using the csoundDestroy API function. Most of the other Csound API functions take the Csound instance as their first argument. Hosts can only call the standalone API functions declared in csound.h.
Here is the complete code for the simplest possible Csound API host, a command-line Csound application:
int main(int argc, char **argv)
{
if (!result)
return (result >= 0 ? 0 : result);
}
All opcodes, including plugins, receive a pointer to their host instance of Csound as the first argument. Therefore, plugins MUST NOT compile, perform, or destroy the host instance of Csound, and MUST call the Csound API function pointers off the Csound instance pointer.
MYFLT sr = csound->
GetSr(csound);
In general, plugins should ONLY access Csound functionality through the API function pointers and public members of the CSOUND_ structure.
