@subsubsection Values From Inferior
|

@cindex values from inferior, with Python
|
||||
@cindex python, working with values from inferior
|
||||
|
||||
@cindex @code{gdb.Value}
|
||||
@value{GDBN} provides values it obtains from the inferior program in
|
||||
an object of type @code{gdb.Value}. @value{GDBN} uses this object
|
||||
for its internal bookkeeping of the inferior's values, and for
|
||||
fetching values when necessary.
|
||||
|
||||
Inferior values that are simple scalars can be used directly in
|
||||
Python expressions that are valid for the value's data type. Here's
|
||||
an example for an integer or floating-point value @code{some_val}:
|
||||
|
||||
@smallexample
|
||||
bar = some_val + 2
|
||||
@end smallexample
|
||||
|
||||
@noindent
|
||||
As result of this, @code{bar} will also be a @code{gdb.Value} object
|
||||
whose values are of the same type as those of @code{some_val}.
|
||||
|
||||
Inferior values that are structures or instances of some class can
|
||||
be accessed using the Python @dfn{dictionary syntax}. For example, if
|
||||
@code{some_val} is a @code{gdb.Value} instance holding a structure, you
|
||||
can access its @code{foo} element with:
|
||||
|
||||
@smallexample
|
||||
bar = some_val['foo']
|
||||
@end smallexample
|
||||
|
||||
Again, @code{bar} will also be a @code{gdb.Value} object.
|
||||
|
||||
For pointer data types, @code{gdb.Value} provides a method for
|
||||
dereferencing the pointer to obtain the object it points to.
|
||||
|
||||
@defmethod Value dereference
|
||||
This method returns a new @code{gdb.Value} object whose contents is
|
||||
the object pointed to by the pointer. For example, if @code{foo} is
|
||||
a C pointer to an @code{int}, declared in your C program as
|
||||
|
||||
@smallexample
|
||||
int *foo;
|
||||
@end smallexample
|
||||
|
||||
@noindent
|
||||
then you can use the corresponding @code{gdb.Value} to access what
|
||||
@code{foo} points to like this:
|
||||
|
||||
@smallexample
|
||||
bar = foo.dereference ()
|
||||
@end smallexample
|
||||
|
||||
The result @code{bar} will be a @code{gdb.Value} object holding the
|
||||
value pointed to by @code{foo}.
