condition_variable实现就可以使用其关于 unique_lock和 mutex的stdlibrary实现的内部知识来执行执行其功能的最有效方式。例如。 libstdc++ 的实现包含这个金块:pthread_cond_clockwait(&_M_cond, __lock.mutex()->native_handle(), //< go right into guts of that unique_lock AND mutex CLOCK_MONOTONIC, &__...
An inquiry directive typically appears in the boolean_static_expression of a selection directive, but it can appear anywhere that a variable or literal of its type can appear. Moreover, it can appear where regular PL/SQL allows only a literal (not a variable)—for example, to specify the ...
variable=operand+another; I think that looks nice, and users have asked for it. For no good reason, when writing the new formatter we didn't do that for conditional expressions. Instead, you get: variable=condition?thenBranch:elseBranch; ...
Set the system variable$tracelogconditionto thelog condition; Execute the command incommand text; Thebreak conditionwill be set to the value of$tracecondition. So if you modify this system variable in the script, you will be able to control whether the debuggee would break. ...

InSection 3.1.1, we introduced conditional variable assignments, which are a shorthand notation for variable assignments within if statements. VHDL similarly provides conditional signal assignments as a shorthand for signal assignment statements within if statements. The syntax rule is similar: ...
The analyzer has detected a potential error in a condition. The program must perform different actions depending on which range of values a certain variable meets.
