Example
The following example shows the usage of fstatvfs() method.
#!/usr/bin/python
import os, sys
# Open a file
fd = os.open( "foo.txt", os.O_RDWR|os.O_CREAT )
# Now get the touple
info = os.fstatvfs(fd)
print "File Info :", info
# Now get maximum filename length
print "Maximum filename length :%d" % info.f_namemax:
# Now get free blocks
print "Free blocks :%d" % info.f_bfree
# Close opened file
os.close( fd)
Let us compile and run the above program, this will produce the following result:
File Info : (4096, 4096, 2621440L, 1113266L, 1113266L,
8929602L, 8764252L, 8764252L, 0, 255)
Maximum filename length :255
Free blocks :1113266

disk.
