Thanks for documenting this in detail. A few suggestions:
- is it really necessary to call odbedit three times? Maybe two or even three functions can be merged. Like you call odbinit, it checks if the environment |

The sizeof checks were originally invented by KO to check for binary compatibility between processes attached to the same ODB and event buffers. So if a
compiler generates different structure sizes due to different padding, one would see that immediately. I wonder however if the absolute numbers make sense |

I agree that the binary compatibility checks are crucial. But I kind of find it strange if one gets an assert failure some where if one tries to change
MAX_CLIENTS. It is then not straight
forward to relate both things and understand the consequences. That's why I put a comment next to the definition of MAX_CLIENTS saying:

The type INT has been defined in 1989 when I for the first time sent data between a 16-bit MS-DOS computer and a 32-bit VAX computer (good old
days!). At that time, uint32_t was not available at all. So much for the historical background.

23 Mar 2018, Stefan Ritt, Bug Report, link to an array element displays whole array in mhttpd 
|
It might have worked some ~5 years ago, but it never really showed the target value of a link, just the
link itself. I reworked the code now to show both the link and the target of the link, so you can change
both in the mhttpd ODB page. Should be consistent now with odbedit. Have a look if it works for you.

18 Apr 2018, Stefan Ritt, Forum, new midas custom features and javascript
|
The function mhttpd_init() scans the custom page and installs handlers etc. for each modbxxx
element. If you create an modbvalue dynamically in your code, this is probably done after you
called mhttpd_init(), so the function has no chance to modify the dynamically created element.

Two options:
1) Do NOT send your events into the ODB. This is controlled via the flag RO_ODB in your frontend setting. For simple experiments with small events, it |
