GDB: break if variable equal value

Question

I like to make GDB set a break point when a variable equal some value I set, I tried this example:

#include 
main()
{ 
     int i = 0;
     fo

There are hardware and software watchpoints. They are for reading and for writing a variable. You need to consult a tutorial:

To set a watchpoint, first you need to break the code into a place where the varianle i is present in the environment, and set the watchpoint.

watch command is used to set a watchpoit for writing, while rwatch for reading, and awatch for reading/writing.
