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 |

We have al_trigger_alarm(), but no matching al_clear_alarm(), and I need it to
clear my alarm once the alarm condition no longer exists. Any objections if I
add this function? K.O. |

I had two free afternoon and took the opportunity to write a new API for the MSCB
system. I'm not sure if anybody else actually uses MSCB (MIDAS slow control bus),
but anyhow.

Thanks. At first blush, a guess, read_passwords() is not thread-safe and is called from multiple threads, not protected by semaphore. Crash report shows |

A long planned modification of the source file structure of the MSCB subsystem has been implemented. This is however only for those people who do actively

project. So whenever a new project was added, this file had to be modified which is clumsy and hard to maintain. Therefore I took the project specific |
