16: This module contains some generic functions for getting the name and version
17: of libwww. It also contains some global configuration options like if you
18: can access the local file system, for example.

30: </H2>
31: <P>
2.7 ! kahan 32: These two functions initialize memory and settings for the libwww core and
2.6 frystyk 33: cleans up memory kept by libwww core when exiting the application. They
34: MUST be used as libwww otherwise is in a undefined state.

39: Libwww Name and Version
40: </H2>
2.1 frystyk 41: <P>
42: You can get the generic name of the Library and the version by using the
43: following functions:
44: <PRE>extern const char * HTLib_name (void);
45: extern const char * HTLib_version (void);

49: </H2>
2.2 frystyk 50: <P>
51: Returns YES or NO

2.6 frystyk 54: <H2>
55: Application Name and Version
56: </H2>
57: <P>
58: Returns the name of the application name and the version number. The name
59: and version SHOULD be short and to the point. They MUST NOT be used for
60: advertising or other non-essential information. Although any token character
61: MAY appear in a product-version, this token SHOULD only be used for a version
62: identifier.

2.6 frystyk 64: Set or get the application name
2.1 frystyk 65: </H3>
66: <P>
2.6 frystyk 67: The name can not contain any spaces as it is used as part of the user agent
68: field. For the same reason, the string MUST be in US-ASCII. For example,
69: "<B>SmartApp</B>"
2.1 frystyk 70: <PRE>

2.6 frystyk 72: extern BOOL HTLib_setAppName (const char * name);
73: </PRE>
74: <H3>
75: Set or get the application version
76: </H3>
77: <P>
78: The version token can not contain any spaces as it is used as part of the
79: user agent field. For the same reason, the string MUST be in US-ASCII. For
80: example, "<B>1.0</B>".

2.6 frystyk 87: </H2>
2.1 frystyk 88: <P>
2.6 frystyk 89: Libwww does normally use the local file system for dumping unknown data objects,
2.7 ! kahan 90: file cache etc. In some situations this is not desired, and we can therefore
2.6 frystyk 91: turn it off. This mode also prevents you from being able to access other
92: resources where you have to login telnet, for example.

2.1 frystyk 99: <P>
100: The default <A HREF="HTUser.html">user profile</A> is automatically created
101: by the libwww in order to get information about the <I>hostname</I>, default
102: <I>email -address </I>etc. All <A HREF="HTReq.html">request objects</A> will
103: be created with this default user profile. The application may assign individual
104: user profiles to every request object or may set the default user profile.
