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