20 | /* ISO C 99 <stdbool.h> for platforms that lack it. */ | ||
21 | |||
22 | /* Usage suggestions: | ||
23 | |||
24 | Programs that use <stdbool.h> should be aware of some limitations | ||
25 | and standards compliance issues. | ||
26 | |||
27 | Standards compliance: | ||
28 | |||
29 | - <stdbool.h> must be #included before 'bool', 'false', 'true' | ||
30 | can be used. | ||
31 | |||
32 | - You cannot assume that sizeof (bool) == 1. | ||
33 | |||
34 | - Programs should not undefine the macros bool, true, and false, | ||
35 | as C99 lists that as an "obsolescent feature". | ||
36 | |||
37 | Limitations of this substitute, when used in a C89 environment: | ||
38 | |||
39 | - <stdbool.h> must be #included before the '_Bool' type can be used. | ||
40 | |||
41 | - You cannot assume that _Bool is a typedef; it might be a macro. | ||
42 | |||
43 | - Bit-fields of type 'bool' are not supported. Portable code | ||
44 | should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'. | ||
45 | |||
46 | - In C99, casts and automatic conversions to '_Bool' or 'bool' are | ||
47 | performed in such a way that every nonzero value gets converted | ||
48 | to 'true', and zero gets converted to 'false'. This doesn't work | ||
49 | with this substitute. With this substitute, only the values 0 and 1 | ||
50 | give the expected result when converted to _Bool' or 'bool'. | ||
51 | |||
52 | - C99 allows the use of (_Bool)0.0 in constant expressions, but | ||
53 | this substitute cannot always provide this property. | ||
54 | |||
55 | Also, it is suggested that programs use 'bool' rather than '_Bool'; | ||
56 | this isn't required, but 'bool' is more common. */ | ||

95 | Use of an enum type, with IRIX cc, leads to a stupid | ||
96 | "warning(1185): enumerated type mixed with another type". | ||
97 | Even the existence of an enum type, without a typedef, | ||
98 | "Invalid enumerator. (badenum)" with HP-UX cc on Tru64. | ||
99 | The only benefit of the enum, debuggability, is not important | ||
