function declaration isn’t a prototype 因为函数原型和调用这个函数时产生了冲突,如参数类型不一样等。 在C中最常见的情况: 这时会出现了 的警告,因为在C语言中my_fn () 和 my_fn (void)是不一样的,前者可以接受任意参数,而后者不接受任何参数。 error: invalid use of void expression 将void函数当成有...
Exact match. An exact match between the types with which the function is called and the types declared in the function prototype is always the best match. Sequences of trivial conversions are classified as exact matches. However, sequences that don't make any of these conversions are considered...

In this case, a prototype for work is given at the beginning of the main function.The parameter function in work is declared to be a pointer to a function taking one int argument and returning a long value. The parentheses around the parameter name are required; without them, the ...
The static specifier signifies that the function can't be referenced from other files; that is, the name isn't exported by the linker. If no storage class appears in a function definition, extern is assumed. In any case, the function is always visible from the definition point to the end...

I don't think this provides significant input into the current question, which has to do with functions (and variables) that are actually declared inline. As for templates, obviously all instantiations can't be emitted in the module unit, but any instantiations that are generated during compilati...
