Quoting from C++ FAQ: Note: It’s imperative that the function’s definition (the part between the {…}) be placed in a header file, unless the function is used only in a single .cpp file. In particular, if you put the inline function’s definition into a .cpp file and you call it from some other .cpp file, … Read more
When the function in the header is not inline, then multiple definitions of this function (e.g. in multiple translation units) is a violation of ODR rules. Inline functions by default have external linkage. Hence, as a consequence of ODR rules (given below), such multiple definitions (e.g. in multiple translation units) are Okay: $3.2/5- “There can … Read more
One solution that is often mentioned is to add the image as an Attachment to the mail, and then reference it in the HTML mailbody using a cid: reference. However if you use the LinkedResources collection instead, the inline images will still appear just fine, but don’t show as additional attachments to the mail. That’s … Read more
This is not Firefox-only, and defined in the CSS 2.1 Specification: 8.3 Margin properties: ‘margin-top’, ‘margin-right’, ‘margin-bottom’, ‘margin-left’, and ‘margin’ Margin properties specify the width of the margin area of a box. The ‘margin’ shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties … Read more
It doesn’t work because vertical-align sets the alignment of inline-level contents with respect to their line box, not their containing block: This property affects the vertical positioning inside a line box of the boxes generated by an inline-level element. A line box is The rectangular area that contains the boxes that form a line When … Read more
Yes ([dcl.constexpr], ยง7.1.5/2 in the C++11 standard): “constexpr functions and constexpr constructors are implicitly inline (7.1.2).” Note, however, that the inline specifier really has very little (if any) effect upon whether a compiler is likely to expand a function inline or not. It does, however, affect the one definition rule, and from that perspective, the … Read more
Yes. From documentation v4.1.2 From documentation latest always_inline Generally, functions are not inlined unless optimization is specified. For functions declared inline, this attribute inlines the function even if no optimization level was specified.
A C code can be optimized in two ways: For Code size and for Execution Time. inline functions: gcc.gnu.org says, By declaring a function inline, you can direct GCC to make calls to that function faster. One way GCC can achieve this is to integrate that function’s code into the code for its callers. This … Read more
to pass the event object: <p id=”p” onclick=”doSomething(event)”> to get the clicked child element (should be used with event parameter: function doSomething(e) { e = e || window.event; var target = e.target || e.srcElement; console.log(target); } to pass the element itself (DOMElement): <p id=”p” onclick=”doThing(this)”> see live example on jsFiddle. You can specify the name … Read more
Python does not have a trailing if statement. There are two kinds of if in Python: if statement: if condition: statement if condition: block if expression (introduced in Python 2.5) expression_if_true if condition else expression_if_false And note, that both print a and b = a are statements. Only the a part is an expression. So … Read more
