有没有可以读取2g以上文件的方法？ 谢谢了

最近在看APUE，lseek不太明白，请大牛讲讲，谢谢

为什么我的lseek老是出错？请高手指点，谢谢！ 错误提示：Invalid argument 代码如下： #include #include #define PATHSIZE 1024 #define BUFFSIZE 1024 int main() { int ret; int filedes; ssize_t size; off_t off; char pathname[PATHSIZE]; char buf[BUFFSIZE]; strcpy(pathname, "test.txt"); filedes = open(pathname, O_RDONLY); if(filedes == -1) { printf("open fail!\n"); ...

offset=0x7fffffff+1; lseek(fd,offset,0); error: Invalid argument. how to fix it?

how to set _FILE_OFFSET_BITS=64? need make kernel again?

#include #include #include int main(void) { int fd; char buf[20]; int size; off_t location; char * filename = "tt.dat"; if( (fd = open(filename,O_RDWR | O_CREAT | O_TRUNC)) == -1){ perror("open"); return 1; } size = write(fd,"Hello C Programming!\n",20); if(size...

int fd; offset_t offset; fd=open("/dev/dsk/c0t1d0s7",O_RDONLY); offset=0x7fffffff+(offset_t)1; lseek64(fd,offset,0); error messages: lseek error, invalid argument. errno:22 if change /dev/dsk/c0t1d0s7 with a large file name(>;2g), it works. how to fix it?
