ARM_Linux多線程編程示例

#include <pthread.h>
#include"reader.h"

void *create(void *arg)
{
while(1)
{
printf("thread is Running ..... ");
sleep(5);
}

}

void *ReaderThread(void *arg)
{
int reader_fd;
char buf[32];

if((reader_fd=OpenReader("/dev/tty0"))==-1)
{
puts("Open Dev Error!\r\n");
}

while(1)
{
if(ReadId(reader_fd,buf,32)==1)
{
printf("Read ID=%s\r\n",buf);
}
}

CloseReader(reader_fd);

}

int main(int argc, char *argv[])
{

int rc1,rc2;

rc1=pthread_create(&tidp,NULL,create,NULL);
if(rc1!=0)
{
printf("pthread_create is not created ... \r\n");
return -1;
}

printf("prthread_create is created... \r\n");
