DosQueryProcType - Parameters

hmod (HMODULE) - input

The handle of the dynamic link module that contains the procedure.

ordinal (ULONG) - input

The ordinal number of the procedure whose type is desired.

If the ordinal number is nonzero, pszName is ignored.

pszName (PSZ) - input

The address of an ASCIIZ name string that contains the procedure name that is being referenced.

Calls to DosQueryProcType for entries within the DOSCALLS module are supported for ordinal references only. References to the DOSCALLS module by name strings are not supported, and will return an error. Dynamic link ordinal numbers for DOSCALLS routines are resolved by linking with OS2386.LIB.

pulproctype (PULONG) - output

The address of a ULONG in which the procedure type is returned.

The value returned in this field is one of the following:

• PT_16BIT Procedure is 16-bit.
  
• PT_32BIT
  Procedure is 32-bit.

ulrc (APIRET) - returns
