usleep(3) during ISR; OPI zero; Debian Stretch

[lve0200]

Hi All, this is my 1st post here. If I'm mistaken where or what placing here, please pardon me and direct me to the right place.

Please illuminate my ignorance, concerning the subject. 

I think it is implementation dependent, how usleep(3) is treated, when found in an interrupt service call back routine.

Is it just ignored?, or are ISRs executed as threads and usleep(3) works??

Moreover, the ISR is called from a Real_Timer int (sigalrm).

Thank's and best regards

Hi,

really no answer?

 I put this here, because since it it implementation dependent, only the developers can know & answer.

It might be the right place to ask, but this is community forum, not technical support for internet. Yes, someone could know what you are asking ... but with bumping the subject you could also lost that opportunity.

BTW. I don't know.
