/FHQ8:  I want to write software for DESQview.  Where can I get the API?/FB



There are multiple sources, ranging in cost from free to hundreds of
dollars.  For free, there are DVINT, a DESQview//QEMM-specific excerpt of
the MSDOS interrupt list, which lists the API calls; and DVGLUE, a
somewhat dated (August 1988) freeware library for Turbo C which
implements almost all of the DESQview 2.01 API (the then-current
version).  Both are available on DVNet and other repositories of
DESQview-specific programs /JB(see Q7)/q7.txt/.



Quarterdeck sells a number of products for programming the DESQview API,
such as an API reference manual (~$60) and various language-specific
libraries (C, Pascal, Dbase, etc., ~$200 each including the reference
manual).  In addition, Quarterdeck also sells a panel designer (~$150),
debugger (~150), and other tools /JB(see Q19)/q19.txt/.  The whole toolkit costs
about $500.  Third party books are also available /JB(see Q20)/q20.txt/.



X Windows libraries for DESQview//X are also available from Quarterdeck.
The pre-release version is about $500.  The DESQview//X API, which is not
completely compatible with the DESQview API, will be available soon.



The DESQview//X development kit will include the Rational System's
DOS//4GX 16- and 32-bit protected mode development kit which supports
Microsoft C and Metaware High C 32-bit.



The prices above are Quarterdeck prices; the price on the street is
usually a lot better.  One source of API tools is the Programmer's
