Chapter 3: Examining Source Files

the current source ﬁle to whatever ﬁle contains the source for the procedure

(see “Examining the Stack” on page 46 for more information on activation

levels).

If you enter the ﬁle command without any arguments, dbx prints the current

source ﬁle:

(dbx) file

procedure.c

You can also change the current source ﬁle by typing:

(dbx) func procedure

You can use the tag command to search the tag ﬁle for procedure:

(dbx) tag procedure

The tag command ﬁnds C preprocessor macros if they have arguments

(func procedure cannot). For more information about the tag ﬁle, seectags(1).

Listing Source Code

Thelist command displays lines of source code. The dbx variable $listwindow

deﬁnes the number of lines dbx lists by default. The list command uses the

active frame and line of the current source ﬁle unless overridden by a ﬁle

command. Any execution of the program overrides the ﬁle command by

establishing a new current source ﬁle.

The syntax for the list command is:

list Lists $listwindow lines beginning at the current line (or list

the line of the current pc if the current line is unknown or

not set).

list exp Lists $listwindow lines starting with the line number given

by the expression exp. The expression can be any valid

expression that evaluates to an integer value as described in

“Using Expressions” on page 33.

list exp1:exp2 Lists exp2 lines, beginning at line exp1.

list exp1,exp2 Lists all source between line exp1 and line exp2 inclusive.
