ISPUNCT(3) BSD Library Functions Manual ISPUNCT(3) NAME
ispunct -- punctuation character test LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int ispunct(int c); DESCRIPTION
The ispunct() function tests for any printing character, except for space (' ') or a character for which isalnum(3) is true. The value of the argument must be representable as an unsigned char or the value of EOF. In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal): 041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%'' 046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*'' 053 ``+'' 054 ``,'' 055 ``-'' 056 ``.'' 057 ``/'' 072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>'' 077 ``?'' 100 ``@'' 133 ``['' 134 ``'' 135 ``]'' 136 ``^'' 137 ``_'' 140 ```'' 173 ``{'' 174 ``|'' 175 ``}'' 176 ``~'' RETURN VALUES
The ispunct() function returns zero if the character tests false and returns non-zero if the character tests true. COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered obsolete and may not be supported in future releases. The iswpunct() function should be used instead. SEE ALSO
ctype(3), isalnum_l(3), iswpunct(3), ascii(7) STANDARDS
The ispunct() function conforms to ISO/IEC 9899:1990 (``ISO C90''). BSD

ISGRAPH(3) BSD Library Functions Manual ISGRAPH(3) NAME
isgraph -- printing character test (space character exclusive) LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int isgraph(int c); DESCRIPTION
The isgraph() function tests for any printing character except space (' ') and other locale-specific space-like characters. The value of the argument must be representable as an unsigned char or the value of EOF. In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal): 041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%'' 046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*'' 053 ``+'' 054 ``,'' 055 ``-'' 056 ``.'' 057 ``/'' 060 ``0'' 061 ``1'' 062 ``2'' 063 ``3'' 064 ``4'' 065 ``5'' 066 ``6'' 067 ``7'' 070 ``8'' 071 ``9'' 072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>'' 077 ``?'' 100 ``@'' 101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E'' 106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J'' 113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O'' 120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T'' 125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y'' 132 ``Z'' 133 ``['' 134 ``'' 135 ``]'' 136 ``^'' 137 ``_'' 140 ```'' 141 ``a'' 142 ``b'' 143 ``c'' 144 ``d'' 145 ``e'' 146 ``f'' 147 ``g'' 150 ``h'' 151 ``i'' 152 ``j'' 153 ``k'' 154 ``l'' 155 ``m'' 156 ``n'' 157 ``o'' 160 ``p'' 161 ``q'' 162 ``r'' 163 ``s'' 164 ``t'' 165 ``u'' 166 ``v'' 167 ``w'' 170 ``x'' 171 ``y'' 172 ``z'' 173 ``{'' 174 ``|'' 175 ``}'' 176 ``~'' RETURN VALUES
The isgraph() function returns zero if the character tests false and returns non-zero if the character tests true. COMPATIBILITY
