Hi,
When I executed below source in qemu-arm user binary, It was failed
with Invalid Argument.
gcc lseek_test.c -o lseek_test -D_FILE_OFFSET_BITS=64
./lseek_test
error: Invalid argument
It seems the qemu-arm user does not support the D_FILE_OFFSET_BITS flag.
Is it a known issue or I had wrong test procedure on qemu-arm user environment?
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <sys/stat.h>
#include <fcntl.h>
int main()
{
int fd, ret;
off_t pos = 2*1024*1024*1024 + 10; // over 2G
fd = open("large_file", O_CREAT | O_WRONLY | O_TRUNC, 0666);
if (fd < 0){
fprintf(stderr, "%s\n", strerror(errno));
exit(1);
}
if (lseek(fd, pos, SEEK_SET) < 0) {
//fprintf(stderr, "Failed seeking to %zu, %d\n", pos, errno);
perror("error");
exit(1);
}
write(fd, "TEST", 4);
close(fd);
close(fd);
return 0;
}
