NAME
       af_errno, af_perror, af_errmsg, af_cleanup - AtFS error handling

SYNOPSIS
       #include <atfs.h>

       int  af_errno

       void af_perror (char *string)

       char*af_errmsg (char *string)

       int  af_cleanup (void)

DESCRIPTION
       af_errno  is the global AtFS error number variable. If an AtFS functions returns with an error, af_errno is set to indicate the appropriate
       error number. It is not cleared upon successful calls.  The af_intro(3) manual page gives an overview of all error codes.

       af_perror produces a short error message of the form described in perror(3). This message will be written to standard error.  If  the  last
       error  encountered  during  an AtFS application was an AtFS-specific error, a corresponding message is generated, otherwise af_perror calls
       perror(3).

       af_errmsg does the same as af_perror but returns the message rather than writing to standard error. The result  string  resides	in  static
       memory and hence will be overwritten on subsequent calls of af_errmsg.

       Af_cleanup  serves as cleanup routine upon premature termination of an AtFS application. It removes temporary files and frees all allocated
       memory.
