bcmp, bcopy, bzero, ffs, index, rindex, strcasecmp, strncasecmp — string
operations
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <strings.h>
int
bcmp(const void *b1, const void *b2, size_t len);
void
bcopy(const void *src, void *dst, size_t len);
void
bzero(void *b, size_t len);
int
ffs(int value);
char *
index(const char *s, int c);
char *
rindex(const char *s, int c);
int
strcasecmp(const char *s1, const char *s2);
int
strncasecmp(const char *s1, const char *s2, size_t len);
DESCRIPTION
These functions all live in the strings.h header file. Except for ffs(),
they operate on strings. index(), rindex(), and strcasecmp() need nul-
terminated strings.
See the specific manual pages for more information.
See string(3) for string functions that follow ANSI X3.159-1989
(“ANSI C89”) or ISO/IEC 9899:1999 (“ISO C99”), bstring(3) for functions
that operate on strings that are not nul-terminated, and bitstring(3) for
bit-string manipulation macros.
