Python method closerange() closes all file descriptors from fd_low (inclusive) to fd_high (exclusive), ignoring errors.This method is introduced in Python version 2.6.
Following is the syntax for closerange() method −
fd_low − This is the Lowest file descriptor to be closed.
fd_high − This is the Highest file descriptor to be closed.
This function is equivalent to −
for fd in xrange(fd_low, fd_high): try: os.close(fd) except OSError: pass
This method does not return any value.
The following example shows the usage of closerange() method.
#!/usr/bin/python import os, sys # Open a file fd = os.open( "foo.txt", os.O_RDWR|os.O_CREAT ) # Write one string os.write(fd, "This is test") # Close a single opened file os.closerange( fd, fd) print "Closed all the files successfully!!"
This would create given file foo.txt and then write given content in that file.This will produce the following result −
Closed all the files successfully!!
