Completions

Use: keepawake --completions <SHELL> to generate a completion script, you will have to install it as appropriate for the specific shell you are using.

C library (experimental)

Built using cargo-c.

# build the library, create the .h header, create the .pc file
$ cargo cbuild --destdir=${D} --prefix=/usr --libdir=/usr/lib64

# build the library, create the .h header, create the .pc file and install all of it
$ cargo cinstall --destdir=${D} --prefix=/usr --libdir=/usr/lib64

See the generated header file for details on the API. See cargo-c for futher details on cargo-c usage.

Notes

Preventing the computer from explicitly sleeping, and/or by closing the lid, is often restricted in various ways by the OS, e.g. Only on AC power, not in any PC running Windows with Modern Standby. Also note that Modern Standby ignores/terminates power requests on DC (Battery) power, PowerSetRequest - Remarks.
