@cindex progspaces in guile
|

@tindex <gdb:progspace>
|
||||
A program space, or @dfn{progspace}, represents a symbolic view
|
||||
of an address space.
|
||||
It consists of all of the objfiles of the program.
|
||||
@xref{Objfiles In Guile}.
|
||||
@xref{Inferiors and Programs, program spaces}, for more details
|
||||
about program spaces.
|
||||
|
||||
Each progspace is represented by an instance of the @code{<gdb:progspace>}
|
||||
smob. @xref{GDB Scheme Data Types}.
|
||||
|
||||
The following progspace-related functions are available in the
|
||||
@code{(gdb)} module:
|
||||
|
||||
@deffn {Scheme Procedure} progspace? object
|
||||
Return @code{#t} if @var{object} is a @code{<gdb:progspace>} object.
|
||||
Otherwise return @code{#f}.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} progspace-valid? progspace
|
||||
Return @code{#t} if @var{progspace} is valid, @code{#f} if not.
|
||||
A @code{<gdb:progspace>} object can become invalid
|
||||
if the program it refers to is not loaded in @value{GDBN} any longer.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} current-progspace
|
||||
This function returns the program space of the currently selected inferior.
|
||||
There is always a current progspace, this never returns @code{#f}.
|
||||
@xref{Inferiors and Programs}.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} progspaces
|

Return a list of all the progspaces currently known to @value{GDBN}.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} progspace-filename progspace
|
||||
Return the absolute file name of @var{progspace} as a string.
|
||||
This is the name of the file passed as the argument to the @code{file}
|
||||
or @code{symbol-file} commands.
|
||||
If the program space does not have an associated file name,
|
||||
then @code{#f} is returned. This occurs, for example, when @value{GDBN}
|
||||
is started without a program to debug.
|
||||
|
||||
A @code{gdb:invalid-object-error} exception is thrown if @var{progspace}
|
||||
is invalid.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} progspace-objfiles progspace
|
||||
Return the list of objfiles of @var{progspace}.
|
||||
The order of objfiles in the result is arbitrary.
|
||||
Each element is an object of type @code{<gdb:objfile>}.
|
||||
@xref{Objfiles In Guile}.
|

A @code{gdb:invalid-object-error} exception is thrown if @var{progspace}
