@findex gdb.lookup_objfile
@defun gdb.lookup_objfile (name @r{[}, by_build_id{]})
Look up @var{name}, a file name or build ID, in the list of objfiles
for the current program space (@pxref{Progspaces In Python}).
If the objfile is not found throw the Python @code{ValueError} exception.
If @var{name} is a relative file name, then it will match any
source file name with the same trailing components. For example, if
@var{name} is @samp{gcc/expr.c}, then it will match source file
name of @file{/build/trunk/gcc/expr.c}, but not
@file{/build/trunk/libcpp/expr.c} or @file{/build/trunk/gcc/x-expr.c}.
If @var{by_build_id} is provided and is @code{True} then @var{name}
is the build ID of the objfile. Otherwise, @var{name} is a file name.
This is supported only on some operating systems, notably those which use
the ELF format for binary files and the @sc{gnu} Binutils. For more details
about this feature, see the description of the @option{--build-id}
command-line option in @ref{Options, , Command Line Options, ld.info,
The GNU Linker}.
@end defun
Each objfile is represented by an instance of the @code{gdb.Objfile}
class.
