QGYOLOBJ does not return Information_Status = 'L' value and it should

The QGYOLOBJ has key 201 as well as a base header that includes the same information as key 201. However, that field, "Information_Status" or Key 201 never includes the 'L' flag (locked). Instead it returns blanks when an object is locked. So either the documentation is incorrect and needs to be changed, or the API is simply missing that functionality. Without this the only way to test for locks is using another API to list all the locks on the object and parse through them. (NOTE: This is a non-SQL App, so the SQL Services aren't beneficial).

    The QGYOLOBJ API is working as designed. The information status field will have a value of 'L' only if the object is locked with an *EXCL (Lock exclusive no read) lock in another thread and the object could not be locked by the QGYOLOBJ API.

    Yes. I have 12 keys being returned, and one of them is the Status.

    However, the object(s) where I'm not seeing the Locked Status are locked with *EXCLRD not just *EXCL so that may be why it isn't returning locked.

    This history behind this requirement is that I am using QUSRUSAT (Retrieve User Space Attributes) which was going into a long-wait when the *USRSPC is locked with *EXCLRD. So I wanted to check that before attempting the QUSRUSAT API. But QGYOLOBJ isn't returning the "L" status when *EXCLRD is being applied to the object, so the routine failed. I'll write a function that calls the List Object Locks API and then check if there's an *EXCL or *EXCLRD hold on the objects and proceed accordingly.

    On your call to the QGYOLOBJ API, are you specifying to return at least one key field?

    The QGYOLOBJ API documentation states that a key field must be returned for the information status field to be returned:
    Information status. Whether the QGYOLOBJ API returns the requested information for this object. If you do not request any keys to be returned, ignore this field.

    QGYOLOBJ API documentation: https://www.ibm.com/docs/api/v1/content/ssw_ibm_i_75/apis/qgyolobj.htm

    Also, the information status field will have a value of 'L' only if the object is locked with an *EXCL (Lock exclusive no read)
    lock in another thread.
