## Detailed Description

This library contains current system resource consumption information.

## RETURN VALUE

The return value is generally specific to the individual function called.

## CONFORMING TO

These functions are as per the withdrawn POSIX.1e draft specification. The following functions are Linux extensions: **kdk\_rti\_get\_mem\_res\_total\_KiB**() and **kdk\_get\_process\_name**().

## SEE ALSO

[**kdk\_rti\_get\_mem\_res\_total\_KiB**(3)](/man/kdk_rti_get_mem_res_total_KiB/3.md) and [**kdk\_get\_process\_name**(3)](/man/kdk_get_process_name/3.md).
