线程创建出错了
void process(char *buf)
{
printf("****---> %s\n" , buf) ;//出错了
int low = 0 ;
int high = strlen(buf) - 1;
sleep(1) ;
}
int main()
{
FILE *srcfp , *destfp ;
static int num = 0 ; ///add up numbers of rows
char buffer[MAXSIZ];
//char *buffer = malloc(MAXSIZ*sizeof(char)) ;
void process(char* buf) ;
if((srcfp = fopen("srcfile" , "r")) == NULL)
{
printf("open srcfile error!\n") ;
exit(1) ;
}
if((destfp = fopen("destfile" , "w+")) == NULL)
{
printf("open or create destfile error!\n") ;
exit(1) ;
}
while((fgets(buffer , MAXSIZ , srcfp)) != NULL)
{
pthread_t threadfd , thread_fd;
num++ ;
printf("%d %s\n" , num ,buffer) ;
buffer[strlen(buffer)-1] = '\0' ;
thread_fd = pthread_create(&threadfd ,NULL, (void *)(&process ), (void*)buffer) ;//这里好像没有穿过去buffer
if(thread_fd == -1 )
{
printf("create pthread failed!\n") ;
exit(1) ;
}
}
}
[解决办法]
void* process(void *buf)
{
printf("****---> %s\n" , (char *)buf) ;//出错了
int low = 0 ;
int high = strlen(buf) - 1;
sleep(1) ;
}
main函数中：void process(char* buf) ;--这个函数声明去掉
thread_fd = pthread_create(&threadfd ,NULL, process , (void*)buffer) ;
[解决办法]
thread_fd = pthread_create(&threadfd ,NULL, (void *)(&process ), (void*)buffer) ;//这里好像没有穿过
改成
thread fd = pthread_create(&htreadfd,NULL,process,(void *)buffer);//
[解决办法]
void process(char *buf)
---->>>> void process(void *buf)
