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.
