this breaks c99 compliance
John
Do you mean C89 compliance? This should compile just fine in C99.
C99 was released 20 years ago, and C89 30 years ago. I'm personally
not interested in supporting either.
The patch can be modified, or used as inspiration, by someone who is
concerned about C89/C99 compliance and would like to see the
watchdog_open() function improved in this way.
variable declarations should always be at the start of the function.
