[LU-13224] Expose lctl get/set/list param functionality in lustreapi

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.14.0, Lustre 2.12.5
• Affects Version/s: Lustre 2.10.8
• Labels: llnl
• Environment: RHEL 7.5
• Assignee: Gian-Carlo Defazio
• Reporter: Gian-Carlo Defazio

Description

Allow applications that need to access the various lustre parameters in sysfs, profs, etc. to call a function from lustreapi.h that behaves similarly to "lctl get_param <param name>" and has the option to return data to any FILE*, so that it can be further processed by the calling application.

The goal is to use the same infrastructure that allows lctl to know where the correct files are without having to create an lctl process for each get, set, and list operation.

The target applications are those that need to continuously monitor lustre, such as LMT.
