Hi,
I am using GPIO inputs on a TS-7600. In the user manual there is a link to nbus.c (https://files.embeddedarm.com/ts-arm-sbc/ts-7600-linux/sources/nbus.c).
Line 248 has the open command:
devmem = open("/dev/mem", O_RDWR|O_SYNC);
I can't find a corresponding "close" command. Is it automatically taken care of when devmem goes out of scope? Or should there be a "close" command somewhere?
Thank you.
