Subject: cangen: use long long in time computation for -g to support >2.1s
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/can-utils.git/commitdiff_plain/667356cc365bc4525daf3c35ebd4e20db495b174

cangen: use long long in time computation for -g to support >2.1s

The computation of nanosleep times for the "-g" option (delay between sends)
overflows when more than 2100ms are given.
