Addresses

The addr is any expression resulting in or usable as an address. The addr may be replaced with a + (plus sign) which displays the contents of the next address in the default format.

Example addresses are:

0xff99

An absolute address 

main

Address of a function 

main+20

Offset from a function address 

&errno

Address of a variable 

str

A pointer-value variable pointing to a string 

Symbolic addresses used to display memory are specified by preceding a name with an ampersand (&). Function names can be used without the ampersand; &main is equal to main. Registers are denoted by preceding a name with a dollar sign ($).
