This is an optimization wrapper around printbuf_memappend() that is useful for appending string literals. Since the size of string constants is known at compile time, using this macro can avoid a costly strlen() call. This is especially helpful when a constant string must be appended many times. If you got here because of a compilation error caused by passing something other than a string literal, use printbuf_memappend_fast() in conjunction with strlen().

def718 |
This function is the most expensive of the available functions for appending string data to a printbuf and should be used only where convenience is more important than speed. Avoid using this function in high performance code or tight loops; in these scenarios, consider using snprintf() with a static buffer in conjunction with one of the printbuf_*append() functions.
