NAME
iscntrl -- control character test LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int iscntrl(int c); DESCRIPTION
The iscntrl() function tests for any control character. 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): 000 NUL 001 SOH 002 STX 003 ETX 004 EOT 005 ENQ 006 ACK 007 BEL 010 BS 011 HT 012 NL 013 VT 014 NP 015 CR 016 SO 017 SI 020 DLE 021 DC1 022 DC2 023 DC3 024 DC4 025 NAK 026 SYN 027 ETB 030 CAN 031 EM 032 SUB 033 ESC 034 FS 035 GS 036 RS 037 US 177 DEL RETURN VALUES
The iscntrl() 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 iswcntrl() function should be used instead. SEE ALSO
ctype(3), isalnum_l(3), iswcntrl(3), ascii(7) STANDARDS
The iscntrl() function conforms to ISO/IEC 9899:1990 (``ISO C90''). BSD
