Python method pathconf() returns system configuration information relevant to a named file.
Following is the syntax for pathconf() method:
os.pathconf(path, name)
This method returns the system configuration information of a file.
The following example shows the usage of pathconf() method.
#!/usr/bin/python import os, sys print "%s" % os.pathconf_names # Retrieve maximum length of a filename no = os.pathconf('a2.py', 'PC_NAME_MAX') print "Maximum length of a filename :%d" % no # Retrieve file size no = os.pathconf('a2.py', 'PC_FILESIZEBITS') print "file size in bits :%d" % no
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 length of a filename :255 file size in bits : 64
