PifMgr_GetProperties function (shlobj_core.h)

[PifMgr_GetProperties is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

Returns a specified block of data from a .pif file.

Syntax

int PifMgr_GetProperties(
  [in, optional]  HANDLE hProps,
  [in, optional]  PCSTR  pszGroup,
  [out, optional] void   *lpProps,
                  int    cbProps,
                  UINT   flOpt
);

Parameters

[in, optional] hProps

Type: HANDLE

A handle to an application's properties. This parameter should be set to the value that is returned by PifMgr_OpenProperties.

[in, optional] pszGroup

Type: PCSTR

A null-terminated string that contains the property group name. It can be one of the following, or any other name that corresponds to a valid .pif extension.

"WINDOWS 286 3.0"

"WINDOWS 386 3.0"

"WINDOWS VMM 4.0"

"WINDOWS NT 3.1"

"WINDOWS NT 4.0"

[out, optional] lpProps

Type: void*

When this function returns, contains a pointer to a PROPPRG structure.

cbProps

Type: int

The size of the buffer, in bytes, pointed to by lpProps.

flOpt

Type: UINT

Set this parameter to GETPROPS_NONE.

Return value

Type: int

Returns NULL if successful. If unsuccessful, the function returns the handle to the application properties that were passed as hProps.

Remarks

If the block is a "named" block, it must be the name of a linked extension inside the .pif file. This can be any predefined name (such as, "WINDOWS 386 3.0") or the name of your own block. You can create your own named data blocks using PifMgr_SetProperties. Named data can also be thought of as raw data, because it is returned to the calling application as it is, without translation.

The size of a named block can be determined by calling PifMgr_GetProperties with cbProps set to 0. No data is copied, but the size of the requested block is returned.

All named blocks can be enumerated by setting pszGroup to NULL. lpProps must be a pointer to a 16-byte buffer to contain the requested block name, and cbProps must be set to the zero-based block index. The return value is the size of the block, or zero if the block is not found.

If you request an unnamed property block by setting the selector of the name parameter to NULL, and the offset is a property group ordinal, then the associated structure is returned. For example, PifMgr_GetProperties(GROUP_TSK) returns a predefined structure that contains all the task-related information in a format that is independent of the .pif file. This is a valuable service because it relieves calling applications from dealing with .pif files that contain a wide variety of sections (known as .pif extensions), when only one is required.
