스레드 프로그래밍 관련해서 질문입니다

안녕하세요. 책 보면서 스레드 부분 공부하고 있는데
컴파일 하면 에러가 나네요.

$ gcc -o thread2 thread2.c -lpthreadthread2.c:10: error: two or more data types in declaration specifiers
thread2.c: In function ‘main’:
thread2.c:29: warning: passing argument 3 of ‘pthread_create’ from incompatible pointer type
thread2.c:33: warning: passing argument 3 of ‘pthread_create’ from incompatible pointer type
아래는 소스 코드입니다
#include <pthread.h>
#include <stdio.h>
struct char_print_parms
{
char character;
int count;
}
void *char_print(void *parameters)
{
struct char_print_parms *p = (struct char_print_parms*)parameters;
int i;
for(i=0;i<p->count;++i)
fputc(p->character, stderr);
return NULL;
}
int main()
{
pthread_t thread1_id;
pthread_t thread2_id;
struct char_print_parms thread1_args;
struct char_print_parms thread2_args;
thread1_args.character = 'x';
thread1_args.count = 30000;
pthread_create(&thread1_id, NULL, &char_print, &thread1_args);
thread2_args.character = 'o';
thread2_args.count = 20000;
pthread_create(&thread2_id, NULL, &char_print, &thread2_args);
pthread_join(thread1_id, NULL);
pthread_join(thread2_id, NULL);
return 0;
}뭐가 잘못된건가요?
Forums:
struct char_print_parms {
struct char_print_parms { char character; int count; };struct 선언 후 ';' 이 빠졌네요...
헉..
그랬군요 ^^;;
감사합니다
