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

65 | enum constants, not only as macros. | ||
66 | It is tempting to write | ||
67 | typedef enum { false = 0, true = 1 } _Bool; | ||
68 | so that gdb prints values of type 'bool' symbolically. But if we do | ||
69 | this, values of type '_Bool' may promote to 'int' or 'unsigned int' | ||
70 | (see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int' | ||
71 | (see ISO C 99 6.3.1.1.(2)). So we add a negative value to the | ||
72 | enum; this ensures that '_Bool' promotes to 'int'. */ | ||
