VALENT info  Overview  Group

The VALENT structure contains information about a registry value. The RegQueryMultipleValues function uses this structure.

typedef struct value_ent {

    LPTSTR   ve_valuename;

    DWORD ve_valuelen;

    DWORD ve_valueptr;

    DWORD ve_type;

}VALENT;

 

Members

ve_valuename
Pointer to a null-terminated string. Before calling RegQueryMultipleValues, set this member to point to the name of a value to retrieve.
ve_valuelen
Specifies the size, in bytes, of the data pointed to by ve_valueptr.
ve_valueptr
Pointer to the data for the value entry. This is a pointer to the value’s data returned in the lpValueBuf buffer filled in by RegQueryMultipleValues.
ve_type
Specifies the type code for the value entry. The type code can be one of the following values:

Value

Meaning

REG_BINARY

Binary data in any form.

REG_DWORD

A 32-bit number.

REG_DWORD_LITTLE_ENDIAN

A 32-bit number in little-endian format. This is equivalent to REG_DWORD.

In little-endian format, a multi-byte value is stored in memory from the lowest byte (the “little end”) to the highest byte. For example, the value 0x12345678 is stored as (0x78 0x56 0x34 0x12) in little-endian format.

Windows NT and Windows 95 are designed to run on little-endian computer architectures. A user may connect to computers that have big-endian architectures, such as some UNIX systems.

REG_DWORD_BIG_ENDIAN

A 32-bit number in big-endian format.

In big-endian format, a multi-byte value is stored in memory from the highest byte (the “big end”) to the lowest byte. For example, the value 0x12345678 is stored as (0x12 0x34 0x56 0x78) in big-endian format.

REG_EXPAND_SZ

A null-terminated string that contains unexpanded references to environment variables (for example, “%PATH%”). It will be a Unicode or ANSI string depending on whether you use the Unicode or ANSI functions.

REG_LINK

A Unicode symbolic link.

REG_MULTI_SZ

An array of null-terminated strings, terminated by two null characters.

REG_NONE

No defined value type.

REG_RESOURCE_LIST

A device-driver resource list.

REG_SZ

A null-terminated string. It will be a Unicode or ANSI string, depending on whether you use the Unicode or ANSI functions.
