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 ar- gument must be representable as an unsigned char or the value of EOF. In the ASCII character set, this includes the following characters (with their numeric values shown 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 re- turns 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 ob- solete and may not be supported in future releases. The iswpunct() func- tion should be used instead. SEE ALSO ctype(3), iswpunct(3), ascii(7) STANDARDS The ispunct() function conforms to ISO/IEC 9899:1990 ("ISO C90"). BSD July 17, 2005 BSD
