I am writing a C program that requires me to change every timestamp of a file (aTime, mTime, cTime, and bTime/crTime) to nanosecond precision.

If I were to do this in terminal, I would run

debugfs -w -R "set_inode_field <[file_inode]> crtime @[time]" [dev_path]
debugfs -w -R "set_inode_field <[file_inode]> crtime_extra [extra]" [dev_path]

But I cannot find a good way to run debugfs in a C program.

I am aware of using utimensat to modify aTime and mTime in code, but do not know of anything for aTime or bTime/crTime.
