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 applica‐ tion 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 stan‐ dard 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.
