New submission from Yang Big <qq519476...@gmail.com>:
Here my code:
2 import sys
3 import ctypes
4
5
6 def hi():
7 class timespec(ctypes.Structure):
8 ┆ """Time specification, as described in clock_gettime(3)."""
9 ┆ _fields_ = (('tv_sec', ctypes.c_long),
10 ┆ ┆ ┆ ┆ ('tv_nsec', ctypes.c_long))
11
12
13 ts = timespec()
14 po = ctypes.pointer(ts)
15
16
17 def main():
18 while True:
19 ┆ test = hi()
20
21 if __name__ == "__main__":
22 sys 2 import sys
3 import ctypes
4
5
6 def hi():
7 class timespec(ctypes.Structure):
8 ┆ """Time specification, as described in clock_gettime(3)."""
9 ┆ _fields_ = (('tv_sec', ctypes.c_long),
10 ┆ ┆ ┆ ┆ ('tv_nsec', ctypes.c_long))
11
12
13 ts = timespec()
14 po = ctypes.pointer(ts)
15
16
17 def main():
18 while True:
19 ┆ test = hi()
20
21 if __name__ == "__main__":
22 sys.exit(main())
run this code, i find that the program occupy more and more VmRss
my python is 2.7.11, in python3 i also find this problem.
Is this normal？I am a newbie with python, not very familiar with some
python's internal principle.
Tanks.
