It would be cool if IBM published the JZOS Jar on Maven central. We have
a centralized company Artifactory server and have uploaded the z/OS
specific Jars like JZOS, RACF etc which is so much better then uploading
to your PC.

Thanks Kirk,
The ibmjzos.jar in my IDE was too back level to show those methods. Now
I'm using 2.4.10 I can see them.

You don't have to assume, the javadoc documents which C library functions
are used.
https://www.ibm.com/docs/en/sdk-java-technology/8?topic=SSYKE2_8.0.0/com.i
bm.java.zsecurity.api.80.doc/com.ibm.jzos/overview-summary.htm
And I'll correct what I said earlier, if you look at the javadoc you will
see that there are now wrappers for several of the C library "*_unlocked"
functions.

Thanks Kirk,
I have multiple threads reading from and writing to a KSDS. After some
reads I need to release the record lock. I can see there is a locate()
method which I assume is a wrapper to flocate() and flocate() releases
all record locks, according to the doc, so I'll try locate().

1) There is no ENDREQ in the ZFile class. The methods are pretty much
derived from the C library I/O functions.
One common thing that ENDREQ is used for is for using a VSAM ACB to
submit jobs to the internal reader and give you back the jobid. JZOS
does have a
class MvsJobSubmitter that does this. It does not expose a low level
VSAM api.
2) There is no fread_unlocked in the ZFile class.
You can use the javadoc or open the class file in an IDE to see
exactly what methods are there.

Is the VSAM ENDREQ functionality available via the JZOS ZFile VSAM
API?
Also I imagine zfile.read() maps to the C fread(), but is there an
equivalent of the C fread_unlocked()? Thanks
