NAME

strings — 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.
