| 33 | It all started when I typed the name of the program on an OS/2 commandline.
|
|---|
| 34 | This program was a not a native OS/2 program, as you might has thougth, but
|
|---|
| 35 | a Win32 program called SOL.EXE, or Solitaire. The first thing that happend
|
|---|
| 36 | was that the Shell, which in my case is 4OS/2, asks the Kernel what type of
|
|---|
| 37 | application this is. Some Programs are Presentation Manager programs, other
|
|---|
| 38 | are VIO (Virtual I/O) programs, while others again are pure full screen
|
|---|
| 39 | programs. So, 4OS/2 needs to know what kindred the program belongs to in
|
|---|
| 40 | order to start it in it's corrected environment.
|
|---|
| 41 | <p>
|
|---|
| 42 | DosQueryAppType is the name of the API telling which type a program has.
|
|---|
| 43 | This 32-bit call thunks to the 16-bit DosQAppType which does. DosQAppType
|
|---|
| 44 | checks if the specified programname has a path. If is has a (absolute) path
|
|---|
| 45 | nothing extra is done to find the file. But, if it hasn't the PATH is
|
|---|
| 46 | searched. If not found the .EXE extention is eventually (if not present)
|
|---|
| 47 | added to the filename and the PATH is researched. Then the Kernel is
|
|---|
| 48 | called, DOSIQAPPTYPE. DOSIQAPPTYPE does a farcall to w_QAppType which in
|
|---|
| 49 | turn thunks to the 32-bit loader function LDRQAppType. (Note that the
|
|---|
| 50 | LDR-prefix is in capital letters. This could be understood as this is an
|
|---|
| 51 | officially exported function from the Loader subsystem.
