[PATCH 05/41] Documentation: ca_function_calls: improve man-like format

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Parsing this file were causing lots of warnings with sphinx,
due to the c function prototypes.

Fix that by prepending them with .. cpp:function::

While here, use the same way we document man-like pages,
at the V4L side of the book and add escapes to asterisks.
