I have been working lately on a Tcl/Tk frontend and the API has not given me any problems. As for OPCODEDIR setting, is it possible to provide an API function in csound.h for doing it (similar to the ones in envvar.h?). I'm using the stdlib setenv() to do it in the frontend, as in the Mac, environment vars only work from the terminal. Perhaps that would be a neat way of setting all csound env vars from a host application on all platforms. Victor > > Ok, so the question is, does the api work for anyone from > a host right now?

at one point i added a setenv/getenv mechanism that last i looked was
#ifdefed out in the api, presumably because i override the clib
functions, but that could easily be changed.
typedef struct Environs
{
char *environmentVariableName;
char *path;
} Environs;
#define MAX_ENVIRONS = 10;
Environs csoundEnv_[10]; // needs to be put in globals struct
int csoundNumEnvs_ = 0; // needs to be put in globals struct
void csoundSetEnv(void *csound, const char
*environmentVariableName, const char *path)
{
int i = 0;
if (!environmentVariableName || !path)
return;
for (i = 0; i < csoundNumEnvs_; i++)
{
if (strcmp(csoundEnv_[i].environmentVariableName,
environmentVariableName) == 0)
{
mrealloc(csoundEnv_[i].path, strlen(path)+1);
strcpy(csoundEnv_[i].path, path);
return;
}
}
if (csoundNumEnvs_ >= MAX_ENVIRONS)
{
warning("Exceeded maximum number of environment paths");
return;
}
csoundEnv_[csoundNumEnvs_].environmentVariableName = mmalloc
(strlen(environmentVariableName)+1);
strcpy(csoundEnv_[csoundNumEnvs_].environmentVariableName,
environmentVariableName);
csoundEnv_[csoundNumEnvs_].path = mmalloc(strlen(path) + 1);
strcpy(csoundEnv_[csoundNumEnvs_].path, path);
csoundNumEnvs_++;
}
char *csoundGetEnv(const char *environmentVariableName)
{
int i;
for (i = 0; i < csoundNumEnvs_; i++)
{
if (strcmp(csoundEnv_[i].environmentVariableName,
environmentVariableName) == 0)
{
return (csoundEnv_[i].path);
}
}
return 0;
}
void csoundClearEnv()
{
int i;
for (i = 0; i < csoundNumEnvs_; i++)
{
mfree(csoundEnv_[i].environmentVariableName);
mfree(csoundEnv_[i].path);
}
csoundNumEnvs_ = 0;
}
/* override gentenv */
char *getenv(const char *envi)
{
return csoundGetEnv(envi);
}

The trick is that there is a hidden directory in your $HOME which is called .MacOSX; Inside this directory there needs to be a file (not created by any app so you will have to make it) called "environment.plist" and that file contains XML flags encapsulating the various environment variables. For example, for a user to use canonical [csoundapi~] in Pd, you could put this as the contents of your ~/.MacOSX/environment.plist : |

Not based on your code, but nevertheless there is this function:
/**
* Set the default value of environment variable 'name' to 'value'.
* It is not safe to call this function while any Csound instances
* are active.
* Returns zero on success.
*/
PUBLIC int csoundSetDefaultEnv(const char *name, const char *value);
As it uses a static array that is shared by all instances of Csound,
this function is only safe to call before any API functions that may
possibly use environment variables. The environment set this way
overrides system environment variables (including those set with
setenv()). value=NULL means deleting the variable, and as a result
making the system variable, if any, available again.
So, this simple host example should work:
CSOUND *csound;
csoundSetDefaultEnv("OPCODEDIR", "/csound5/plugins");
csound = csoundCreate(NULL);
if (csoundCompile(csound, argc, argv) == 0) {
while (!csoundPerformKsmps(csound));
}
csoundDestroy(csound);

OSX, but hopefully will test on Linux and Windows soon. I can have a look at your example, but it will have to be more towards the end of the week. Perhaps Istvan can test it sooner.

So yeah, don't sweat the testing, got it fixed up again. I am curious as to why you chose Tcl/TK to do yours, is that because PD uses it? Eventually I think it would be great to have examples available in a number of languages, I will be doing mine in C and Python.
