NAME
af_afname, af_afpath, af_aftype, af_afuser, af_setarchpath, af_version - miscellaneous AtFS functions SYNOPSIS
#include <atfs.h> char *af_afname (char *path) char *af_afpath (char *path) char *af_aftype (char *path) Af_user*af_afuser (uit_t uid) char *af_setarchpath (char *path) char *af_version (void) DESCRIPTION
The functions af_afname, af_afpath and af_aftype extract name, syspath or type from a given (operating system dependent) file identifica- tion. In an UNIX environment, a given pathname of the form /usr/lib/libatfs.a leads to afname libatfs, afpath /usr/lib and aftype a. If no path (eg. otto.c), or no type (eg. /usr/hugo/Makefile) is given, the corresponding routine returns an empty string. A period as first character in a filename is always considered to be part of the name (e.g. .cshrc has the name .cshrc and an empty type string). "." and ".." are recognized as names. Archive file extensions and AtFS specific path extensions are stripped from the resulting name resp. pathname. Note: af_afname, af_afpath and af_aftype use static memory for the returned results. Subsequent calls of the same function overwrite for- mer results. af_afuser returns an AtFS user identification which consists of the login name of the user identified by uid, the current host and the cur- rent domain. Uid_t is defined according to the return type of getuid (2) on your system. The Af_user type has the following structure typedef struct { charaf_username[MAXUSERNAMELEN]; charaf_userhost[MAXHOSTNAMELEN]; charaf_userdomain[MAXDOMAIN+1]; } Af_user; af_setarchpath defines the location of the AtFS archive files. A nil-pointer given as path-argument clears the former setting of the global archive path. af_setarchpath returns the old global archive path. Initially, no global archive path is set. In this case, all archive files are stored in a subdirectory called AtFS, relative to the directory where corresponding busy version resides. af_version returns a string that names the version and the creator of the currently used AtFS library.

NAME
atUserValid, atScanUser, atUserName, atUserUid - user handling SYNOPSIS
#include <atfs.h> #include <atfstk.h> void atScanUser (char *userName; Af_user *resultUser); char* atUserName (Af_user *user); Uid_t atUserUid (Af_user *user); int atUserValid (Af_user *user); DESCRIPTION
atScanUser scans the given string userName and tries to derive an AtFS user identification (resultUser) from it. It does not verify the existence of a corresponding UNIX (/etc/passwd) user entry. Use atUserUid to test that. atScanUser understands the following formats: user When the string does not contain an at sign, it is considered to be a plain user name from the current host and domain. user@host In the case that the part after the at sign doe not contain a period, it is assumed to be a hostname. Domain is the current domain. user@host.domain This format can only be recognized, when the given domain is equal to the current domain, and the hostname remains as rest between the at sign and domain name. user@domain An user identification string with a domain name different to the local domain is treated as user@domain, although this might be wrong. atUserName returns a string of the form user@domain generated from the given user structure. If no domain name is given in the structure, it returns user@host instead. With no host and no domain name, just user is returned. The result string resides in static memory and will be overwritten on subsequent calls. atUserUid tries to map the given user structure to a UNIX user identification. It returns the uid on success, -1 otherwise. atUserValid checks the given user structure for plausibility. It returns FALSE on fauilure, a non null value on success.
