int main(int argc, const char *argv[])
{
struct stat st;
#ifdef _FILE_OFFSET_BITS
printf("_FILE_OFFSET_BITS=%d\n",_FILE_OFFSET_BITS);
#endif
if (stat(argv[1], &st) != 0)
{
perror("Error calling stat");
}
printf("stat ok\n");
return 0;
}
当stat file >2G 在Linux会出现
Error calling stat: Value too large for defined data type
解决方法是：
#define _FILE_OFFSET_BITS 64
#include <sys/stat.h>
