2021年12月25日 · From the C Standard (7.2 Diagnostics <assert.h>) 1 The header <assert.h> defines the assert and static_assert macros and refers to another macro, NDEBUG which is not defined by <assert.h>. If NDEBUG is defined as a macro name at the point in the source file where <assert.h> is included, the assert macro is defined simply as

2013年12月3日 · An assertion checks a boolean-typed expression that must be true during program runtime execution. The assertion facility can be enabled or disable at runtime.

2018年8月6日 · Reading a hardware bus specification, I frequently come across things like: "When the controller sees that a bus request has been made, it asserts the Bus Grant line to the first device." What ex...
