pthread problem related to c++

[david wolf]

The following pthread code cannot compile, I want to know why. Can
somebody give me direction on this?

if I replace the following line of code

status1 = pthread_create( &threadID1, NULL, read, NULL);

with:

status1 = pthread_create( &threadID1, NULL, readerWriter::r ead, NULL);

It cannot compile either, how to make it to be compiled?

Thanks,

David
----------------cannot compile, want to know why-------
#include <pthread.h>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

class readerWriter{
public:
void *read(void *ptr);
void createThreads() ;
};

void *readerWriter:: read(void *ptr){

cout<<"read letter "<<endl;

return NULL;
}

void readerWriter::c reateThreads(){
pthread_t threadID1;
int status1;
//status1 = pthread_create( &threadID1, NULL, readerWriter::r ead,
NULL);
status1 = pthread_create( &threadID1, NULL, read, NULL);
status1 = pthread_join(th readID1, NULL);
}

int main(){
readerWriter rw;
rw.createThread s();

return 0;
}
