There was a problem hiding this comment.
I did not understand the usage of break here?
If num_asic is not greater than 0, then what might happen?
In what scenario will this check be useful?
Previously, we were breaking after parsing the line starting with "NUM_ASIC=", we could still do the same without check for the value?

#### Why I did it Avoid 'sscanf()' for number conversions. Its use can lead to undefined behavior, slow processing, and integer overflows. Instead prefer the 'strto*()' family of functions. #### How I did it replace sscanf with strtol #### How to verify it Manual test
