| # Evaluating and printing expressions in zxdb |
| |
| The `print` command can evaluate simple C/C++ expressions in the context of a stack frame. When a |
| thread is suspended (see “Working with threads” above) just type: |
| |
| ``` |
| [zxdb] print i |
| 34 |
| ``` |
| |
| Expressions can use most simple C/C++ syntax: |
| |
| ``` |
| [zxdb] print &foo->bar[baz] |
| (const MyStruct*) 0x59f4e1268f70 |
| |
| ``` |
| |
| You can also evaluate expressions in the context of other stack frames without switching to them |
| (see “Interaction model” above for more): |
| |
| ``` |
| [zxdb] frame 2 print argv[0] |
| "/bin/cowsay" |
| ``` |
| |
| Often you will want to see all local variables: |
| |
| ``` |
| [zxdb] locals |
| argc = 1 |
| argv = (const char* const*) 0x59999ec02dc0 |
| ``` |
| |
| You can also set variables: |
| |
| ``` |
| [zxdb] print done_flag = true |
| true |
| [zddb] print i = 56 |
| 56 |
| ``` |
