Have a look at this code : (also included as an attachment to avoid
mail-spaghetti)
-------- cut here --------
#include <stdio.h>
#include <pthread.h>
void TheThread (char *Text) {
printf("text: %s\n",Text);
pthread_exit("lalala");
}
int main(int argc, char *argv[]) {
pthread_t ThreadID;
const char Hello[] = "Hello world!";
char *ReturnString;
// Start the thread...
pthread_create(&ThreadID,NULL,(pthread_startroutine_t)&TheThread,&Hello);
// Wait for the thread to exit
pthread_join(ThreadID,(void **)&ReturnString);
printf("return value: %s\n",ReturnString);
return 0;
}
-------- cut here --------
compile with :
gcc -Wall -pthread test.c -o test
grtz!
