GetFieldValue macro (wdbgexts.h)

  • Article

The GetFieldValue macro is a thin wrapper around the GetFieldData function. It is provided as a convenience for reading the value of a member in a structure.

Syntax

void GetFieldValue(
   Addr,
   Type,
   Field,
   OutValue
);

Parameters

Addr

Specifies the address of the structure in the target's memory.

Type

Specifies the name of the type of the structure. This can be qualified with a module name, for example, mymodule!mystruct.

Field

Specifies the name of the member in the structure. Submembers can be specified by using a period-separated path, for example, "myfield.mysubfield".

OutValue

Specifies the object into which the member's value is read.

Return value

None

Remarks

The parameters provided to this macro are the same as those provided to the GetFieldData function except that instead of providing a pointer to a buffer and its size, the variable to hold the returned value can be provided directly.

Returns

If the function succeeds, the return value is zero. Otherwise, the return value is one of the IG_DUMP_SYMBOL_INFO error code.
