Ah, it was a shortcut, sorry. You are right, uswsusp (ie. the userland tools themselves) takes the swap from the configuration file (or command line), but if one is defined in /sys/power/resume (or in the kernel command line), you can check it with the SNAPSHOT_AVAIL_SWAP ioctl. However, this only works if /dev/snapshot is open for reading.
