74 Chapter 10. Examining Data
Other settings control how different kinds of objects are printed:
set print array
set print array on
Pretty print arrays. This format is more convenient to read, but uses more space. The default is
off.
set print array off
Return to compressed format for arrays.
show print array
Show whether compressed or pretty format is selected for displaying arrays.
set print elements
number-of-elements
Set a limit on how many elements of an array gdb will print. If gdb is printing a large array,
it stops printing after it has printed the number of elements set by the
set print elements
command. This limit also applies to the display of strings. When gdb starts, this limit is set to
200. Setting
number-of-elements
to zero means that the printing is unlimited.
show print elements
Display the number of elements of a large array that gdb will print. If the number is 0, then the
printing is unlimited.
set print null-stop
Cause gdb to stop printing the characters of an array when the first null is encountered. This is
useful when large arrays actually contain only short strings. The default is off.
set print pretty on
Cause gdb to print structures in an indented format with one member per line, like this:
$1 = {
next = 0x0,
flags = {
sweet = 1,
sour = 1
},
meat = 0x54 "Pork"
}
set print pretty off
Cause gdb to print structures in a compact format, like this:
$1 = {next = 0x0, flags = {sweet = 1, sour = 1}, \
meat = 0x54 "Pork"}
This is the default format.
show print pretty
Show which format gdb is using to print structures.
