title: Is the term "libc" equivalent to "C standard library"?
body: <p>I sometimes hear people using the terms "libc" and "C standard library" interchangeably. I understand that "libc" is the name (or part of the names) of many popular C standard library implementations. My guess is that because of the widespread use of these implementations, people started referring to the C standard library in general as "libc" although it is not an official name. </p>
  
  <p>Is it correct to refer to the C standard library as "libc"?</p>
