SplQpQueryDt

SplQpQueryDt returns a list of supported data types.

Syntax

 SplQpQueryDt(pcDatatypes, papszDatatypes);

Parameters

pcDatatypes (PLONG) - input

A pointer to a value indicating the maximum number of data types. On return, the value is updated to show the number of data types returned.

papszDatatypes (PSZ) - input

A pointer to an array of pointers that address the locations for the returned data type names. Each location must be an array of 16 characters to accommodate a name of the maximum length with its terminating NULL.

Return Code

fSuccess (BOOL) - returns

Return codes.

On completion, the handling routine must return BOOLEAN (fSuccess).

• TRUE Success
• FALSE Error

Remarks

This function should be called once with pcDatatypes set to 0 to determine the number of data types. The array papszDatatypes is not updated in this instance. The application can then allocate storage for the array and call the function a second time to return a list of supported data types.

Example Code

#include <os2.h>

PLONG    pcDatatypes;
PSZ      papszDatatypes;
BOOL     fSuccess;        /*  Return codes. */

fSuccess = SplQpQueryDt(pcDatatypes, papszDatatypes);
