Two global definitions are required, and then
one library man page is produced for each export_func definition
that is found. It is generally convenient to place these definitions
as `getdefs' comments (see section Invoking getdefs) near the procedure
definition, but they may also be a separate AutoGen definitions file
(see section Definitions File). Each function will be cross referenced
with their sister functions in a `SEE ALSO' section. A global
see_also definition will be appended to this cross referencing text.
The two global definitions required are:
library | This is the name of your library, without the `lib' prefix.
The AutoOpts library is named `libopts.so...', so the | |
header | Generally, using a library with a compiled program entails
|
The export_func definition should contain the following attributes:
name | The name of the procedure the library user may call. | |
what | A brief sentence describing what the procedure does. | |
doc | A detailed description of what the procedure does. It may ramble on for as long as necessary to properly describe it. | |
err | A short description of how errors are handled. | |
ret_type | The data type returned by the procedure.
Omit this for | |
ret_desc | Describe what the returned value is, if needed. | |
private | If specified, the function will not be documented. This is used, for example, to produce external declarations for functions that are not available for public use, but are used in the generated text. | |
arg | This is a compound attribute that contains: |
arg_type | The data type of the argument. | ||
arg_name | A short name for it. | ||
arg_desc | A brief description. |
As a `getdefs' comment, this would appear something like this:
/*=--subblock=arg=arg_type,arg_name,arg_desc =*/ /*=* * library: opts * header: your-opts.h =*/ /*=export_func optionProcess * * what: this is the main option processing routine * arg: + tOptions* + pOpts + program options descriptor + * arg: + int + argc + program arg count + * arg: + char** + argv + program arg vector + * ret_type: int * ret_desc: the count of the arguments processed * * doc: This is what it does. * err: When it can't, it does this. =*/ |
Note the subblock and library comments.
subblock is an embedded `getdefs'
option (see section subblock option) that tells it how to parse the
arg attribute. The library and header entries
are global definitions that apply to all the documented functions.
