# Description
|
|||
|
|
# -----------
|
|||
|
|
# In this example, we assume that we found
|
|||
|
|
# the ``main`` function at address 0x402A00
|
|||
|
|
# and we add a static symbol to the binary
|
|||
|
|
# so that we can do:
|
|||
|
|
#
|
|||
|
|
# (gdb) break main
|
|||
|
|
# Breakpoint 1 at 0x402a00
