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.
