GNU Info (gdb.info)ListPrinting source lines ===================== To print lines from a source file, use the `list' command (abbreviated `l'). By default, ten lines are printed. There are several ways to specify what part of the file you want to print. Here are the forms of the `list' command most commonly used: `list LINENUM' Print lines centered around line number LINENUM in the current source file. `list FUNCTION' Print lines centered around the beginning of function FUNCTION. `list' Print more lines. If the last lines printed were printed with a `list' command, this prints lines following the last lines printed; however, if the last line printed was a solitary line printed as part of displaying a stack frame (Note: Examining the Stack.), this prints lines centered around that line. `list -' Print lines just before the lines last printed. By default, GDB prints ten source lines with any of these forms of the `list' command. You can change this using `set listsize': `set listsize COUNT' Make the `list' command display COUNT source lines (unless the `list' argument explicitly specifies some other number). `show listsize' Display the number of lines that `list' prints. Repeating a `list' command with <RET> discards the argument, so it is equivalent to typing just `list'. This is more useful than listing the same lines again. An exception is made for an argument of `-'; that argument is preserved in repetition so that each repetition moves up in the source file. In general, the `list' command expects you to supply zero, one or two "linespecs". Linespecs specify source lines; there are several ways of writing them, but the effect is always to specify some source line. Here is a complete description of the possible arguments for `list': `list LINESPEC' Print lines centered around the line specified by LINESPEC. `list FIRST,LAST' Print lines from FIRST to LAST. Both arguments are linespecs. `list ,LAST' Print lines ending with LAST. `list FIRST,' Print lines starting with FIRST. `list +' Print lines just after the lines last printed. `list -' Print lines just before the lines last printed. `list' As described in the preceding table. Here are the ways of specifying a single source line--all the kinds of linespec. `NUMBER' Specifies line NUMBER of the current source file. When a `list' command has two linespecs, this refers to the same source file as the first linespec. `+OFFSET' Specifies the line OFFSET lines after the last line printed. When used as the second linespec in a `list' command that has two, this specifies the line OFFSET lines down from the first linespec. `-OFFSET' Specifies the line OFFSET lines before the last line printed. `FILENAME:NUMBER' Specifies line NUMBER in the source file FILENAME. `FUNCTION' Specifies the line that begins the body of the function FUNCTION. For example: in C, this is the line with the open brace. `FILENAME:FUNCTION' Specifies the line of the open-brace that begins the body of the function FUNCTION in the file FILENAME. You only need the file name with a function name to avoid ambiguity when there are identically named functions in different source files. `*ADDRESS' Specifies the line containing the program address ADDRESS. ADDRESS may be any expression. automatically generated by info2www version 1.2.2.9 |
