af_history(3)						    Attribute Filesystem (AtFS) 					     af_history(3)

NAME

       af_histories, af_access - AtFS history functions

SYNOPSIS

       #include <atfs.h>

       char**af_histories (char *path, char *pattern)

       char**af_cachenames (char *path, char *pattern);

       int   af_access (char *path, char *name, char *type, int mode)

DESCRIPTION

       af_histories  returns  a  list  of source history names from the directory pointed to by path, that match the given pattern. Histories in a
       directory are represented by at least one version. The pattern must be ed(1)  patterns,	processable  by  re_comp(3)  and  re_exec(3).  The
       resulting  list of af_histories resides in allocated memory. Use free(3) to free the memory for further allocation. af_histories returns an
       empty list (not a NULL pointer !), when no histories are found.

       af_cachenames does the same as af_histories but on derived object caches.

       af_access determines the existence of an object history.  If any ASO (any version) with the given path, name and  type  attributes  exists,
       af_access returns zero, otherwise -1.  The mode argument can either be

       AF_CLASS_SOURCE
		 indicating that only source objects shall be searched or

       AF_CLASS_DERIVED
		 which means that only the derived object cache shall be searched for existence of a matching ASO.

DIAGNOSTICS

       Upon error, -1 or a null pointer (depending on the return type) is returned and af_errno is set to the corresponding error number.
