__cdump()

The __cdump() function generates a formatted dump of the Language Environment runtime environment. Output from __cdump() is normally written to the ddname CEEDUMP. The call to __cdump() does not cause your application to terminate. For an example of a formatted dump, see z/OS Language Environment Debugging Guide. The __cdump() function can be called by your application when you want:

A trace of calls so you can see the order in which applications were called
Condition information
Entry information
Stack frame contents
Storage around each register (96 bytes)

If your application runs in a non-fork()ed address space, the CEEDUMP DD statement specifies the name of the dump file. If your application runs in the z/OS UNIX environment, the CEEDUMP DD can contain the PATH= keyword, which specifies the fully qualified path and file name.
