Did you build with -DUSE_DOUBLE ? Otherwise that is where you are  
going wrong.

I did:

gcc -Wall -c basic.c
gcc -Wall basic.o /usr/lib/libcsound64.so.5.1 -DUSE_DOUBLE -o basic

is this correct?

Not correct. You need -DUSE_DOUBLE in all compiler commands. Either  do this:

gcc -Wall -DUSE_DOUBLE -c basic.c
gcc -Wall basic.o /usr/lib/libcsound64.so.5.1 -DUSE_DOUBLE -o basic

Or do this:

gcc -Wall basic.c /usr/lib/libcsound64.so.5.1 -DUSE_DOUBLE -o basic

Hope this helps,
MIke

No you need to use the flag in compilation

gcc -Wall -c basic.c -DUSE_DOUBLE

Does anyone know how to use multiple threads? At the moment I can only change one variable, ideally, I would like to be able to control more. I tried editing the code but with no success. Any help with this would be very much appreciated.

If you want to control more variables in Csound you don't need to use
multiple threads. You only need to use more channels.

Okay, I tried this (with an extra channel) but it didn't work as expected:

#include 
#include "H/csound.h"

uintptr_t csThread(void *clientData);

typedef struct {
int result; //result of csoundCompile()
CSOUND* csound; //instane of Csound
int PERF_STATUS; //tells us if Csound is running
}userData;

//------------------------------------------------------------
int main(int argc, char *argv[])
{
int userInput=200;
int userInputtwo=440;
void* ThreadID;
userData* ud;
ud = (userData *)malloc(sizeof(userData));
MYFLT* pvalue;
MYFLT* pvaluetwo;
ud->csound=csoundCreate(NULL);
csoundInitialize(&argc, &argv, 0);
ud->result=csoundCompile(ud->csound,argc,argv);
if(!ud->result)
{
ud->PERF_STATUS=1;
ThreadID = csoundCreateThread(csThread, (void*)ud);
}
else
{
printf("csoundCompiled returned an error");
return 0;
}
printf("\nEnter a pitch in Hz(0 to Exit) and type return\n");
while(userInput!=0)
{
while(userInputtwo!=0)
{
if(csoundGetChannelPtr(ud->csound, &pvalue, "pitch", CSOUND_INPUT_CHANNEL | CSOUND_CONTROL_CHANNEL)==0);
*pvalue = (MYFLT)userInput;
scanf("%d", &userInput);

if(csoundGetChannelPtr(ud->csound, &pvaluetwo, "pitchtwo", CSOUND_INPUT_CHANNEL | CSOUND_CONTROL_CHANNEL)==0);
*pvaluetwo = (MYFLT)userInputtwo;
scanf("%d", &userInputtwo);
}
}
ud->PERF_STATUS=0;
return ud->result;
}
//-------------------------------------------------------------
