Value:

do {                                           \
        if (!(cond))                                                        \

        fprintf(stderr, "%s:%d: conditional breakpoint fired: "             \
                "CL_BREAK_IF(%s)\n", __FILE__, __LINE__, #cond);            \
                                                                            \

    } while (0)

conditional variant of CL_TRAP, do nothing as long as cond is not satisfied

Attention

the macro suffer from the same flaw as std::assert - the given expression is not evaluated at all unless you're running a debug build

Note

the macro has exactly opposite semantic than std::assert

for comfortable source code browsing, it's recommended to tweak your editor, in order to highlight CL_BREAK_IF as as keyword, as well as CL_TRAP

#define CL_TRAP

jump to debugger by default in case anything interesting happens

Note

this behavior may be subject for change in the future
