NAME

AtFSTK - introduction to the AtFS (Attribute Filesystem) Toolkit Library  

SYNOPSIS

#include <atfs.h>
#include <atfstk.h>

char* atVersion (void);

void atError (int code; char *msg);
int atErrno;
char *atErrMsg;

int atBindError;
char atBindErrorMsg[];

 

DESCRIPTION

The AtFS Toolkit library (AtFStk) is a library of functions defined on top of the Attribute Filesystem (AtFS). It is designed to facilitate the contruction of AtFS application programs.

atVersion returns a version identification string for the AtFS Toolkit library.

atError assigns the given error code and the error message msg to the global variables atErrno and atErrMsg. Note: The given error message string (msg) is not copied. atError just assigns its address to atErrMsg. The application has to care about the persistence of the message buffer assigned to atErrMsg.

atBindError is a flag indicating that something went wrong during the execution of a function from the version binding subsystem (see atbind(3) and atbindrule(3)). When atBindError is set TRUE, atBindErrorMsg holds an explaining error message. The atBindError flag is cleared upon successfull calls, the message buffer remains unchanged.
