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.
