51 | .Sh DESCRIPTION |
52 | The | |
224c7076 A |
53 | .Fn ispunct |
54 | function tests for any printing character, except for space | |
55 | .Pq Ql "\ " | |
56 | or a | |
57 | character for which | |
58 | .Xr isalnum 3 | |
59 | is true. | |
60 | For single C | |
61 | .Va char Ns s | |
62 | locales (see | |
63 | .Xr multibyte 3 ) , | |
64 | the value of the argument is | |
65 | representable as an | |
66 | .Li unsigned char | |
67 | or the value of | |
68 | .Dv EOF . | |
69 | In the ASCII character set, this includes the following characters | |
70 | (preceded by their numeric values, in octal): | |
5b2abdfb | 71 | .Pp |
224c7076 A |
72 | .Bl -column \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__ |
73 | .It "\&041\ ``!'' \t042\ ``""'' \t043\ ``#'' \t044\ ``$'' \t045\ ``%''" | |
74 | .It "\&046\ ``&'' \t047\ ``''' \t050\ ``('' \t051\ ``)'' \t052\ ``*''" | |
75 | .It "\&053\ ``+'' \t054\ ``,'' \t055\ ``-'' \t056\ ``.'' \t057\ ``/''" | |

e9ce8d39 | 81 | .Sh RETURN VALUES |
5b2abdfb | 82 | The |
224c7076 A |
83 | .Fn ispunct |
84 | function returns zero if the character tests false and | |
85 | returns non-zero if the character tests true. | |
86 | .Sh COMPATIBILITY | |
87 | The | |
88 | .Bx 4.4 | |
89 | extension of accepting arguments outside of the range of the | |
90 | .Vt "unsigned char" | |
91 | type in locales with large character sets is considered obsolete | |
92 | and may not be supported in future releases. | |
e9ce8d39 | 93 | The |
224c7076 A |
94 | .Fn iswpunct |
95 | function should be used instead. | |
