Python method fpathconf() returns system configuration information relevant to an open file. This variable is very similar to Unix system call fpathconf() and accepts similar arguments.
Following is the syntax for fpathconf() method:
os.fpathconf(fd, name)
This method returns system configuration information relevant to an open file.
The following example shows the usage of fpathconf() method.
#!/usr/bin/python import os, sys # Open a file fd = os.open( "foo.txt", os.O_RDWR'os.O_CREAT ) print "%s" % os.pathconf_names # Now get maximum number of links to the file. no = os.fpathconf(fd, 'PC_LINK_MAX') print "Maximum number of links to the file. :%d" % no # Now get maximum length of a filename no = os.fpathconf(fd, 'PC_NAME_MAX') print "Maximum length of a filename :%d" % no # Close opened file os.close( fd) print "Closed the file successfully!!"
When we run the above program, it produces the following result:
{'PC_MAX_INPUT': 2, 'PC_VDISABLE': 8, 'PC_SYNC_IO': 9, 'PC_SOCK_MAXBUF': 12, 'PC_NAME_MAX': 3, 'PC_MAX_CANON': 1, 'PC_PRIO_IO': 11, 'PC_CHOWN_RESTRICTED': 6, 'PC_ASYNC_IO': 10, 'PC_NO_TRUNC': 7, 'PC_FILESIZEBITS': 13, 'PC_LINK_MAX': 0, 'PC_PIPE_BUF': 5, 'PC_PATH_MAX': 4} Maximum number of links to the file. :127 Maximum length of a filename :255 Closed the file successfully!!
