The debugging kernel for OS/2 allows this kind of functionality, but I warn
you that tracing every API call will be painfully slow.  You need some
knowledge about the internal symbols used by the kernel, but the
documentation for the debugging kernel (KDEBUG.INF) gives you this.

The debugging kernel itself comes hidden as a part of the distribution of
OS/2 on CD-ROM, in a DEBUG subdirectory.  There is also a *.SYM file there
which was generated by IBM when the kernel was built, and it allows the
debugging kernel to matcg symbols with addresses automatically.  You must
have the debugging kernel which corresponds exactly to the production
kernel which works on your machine; you cannot, for example, use the 8.200
debugging kernel if you have installed FixPack 17 and brought the
production kernel to 8.241.  (The debugging kernel for 8.241 is available
on special request from IBM, and I do have it.)
