1 /* A C macro for emitting warnings if a function is used.
17 /* _GL_WARN_ON_USE (function, "literal string") issues a declaration
18 for FUNCTION which will then trigger a compiler warning containing
19 the text of "literal string" anywhere that function is called, if
23 This macro is useful for marking a function as a potential

26 instead. However, one of the reasons that a function is a
28 FUNCTION with a different signature in C is a compilation error, so
30 that programs that avoid the problematic FUNCTION do not fail to
32 function. But this implies that _GL_WARN_ON_USE is only safe to
33 use if FUNCTION is known to already have a declaration. Use of
35 the declaration of FUNCTION; but undefining FUNCTION first is part
39 C++, it is only safe to use if FUNCTION has no overloads.
