98
99 If TEXT_EXPR fails to hold we return from the enclosing function and
100 print an error, either via adding an error on the given context CTXT
101 if CTXT is non-NULL, falling back to simply printing to stderr if CTXT
102 is NULL.
103
104 They have to be macros since they inject their "return" into the
105 function they are placed in.
106
107 The variant macros express:
108
109 (A) whether or not we need to return a value:
110 RETURN_VAL_IF_FAIL* vs
111 RETURN_IF_FAIL*,
112 with the former returning RETURN_EXPR, and
113 RETURN_NULL_IF_FAIL*
114 for the common case where a NULL value is to be returned on
115 error, and
116
117 (B) whether the error message is to be directly printed:
118 RETURN_*IF_FAIL
119 or is a format string with some number of arguments:
120 RETURN_*IF_FAIL_PRINTF*
121
122 They all use JIT_BEGIN_STMT/JIT_END_STMT so they can be written with
123 trailing semicolons.
