NAME

       rangecheck.h - pointer range checking

SYNTAX

       #include <rangecheck.h>

       int range_validbuf(const void* buf,size_t len);

       int range_ptrinbuf(const void* buf,size_t len,const void* ptr);

       int range_bufinbuf(const void* buf1,size_t len1,
			  const void* buf2,size_t len2);

       int range_arrayinbuf(const void* buf,size_t len,
			    const void* arraystart,
			    size_t elements,size_t membersize);

       int range_strinbuf(const void* buf,size_t len,const void* string);

       int range_str2inbuf(const void* buf,size_t len,const void* string);

       int range_str4inbuf(const void* buf,size_t len,const void* string);

DESCRIPTION

       rangecheck.h  provides several routines for range checking pointers.  These routines are meant for code that has to validate the syntax and
       semantics of buffers coming in from untrusted sources (like a network connection or an input file).

RETURN VALUE

       The routines all return 0 on error, or 1 if the pointers were in range.

NAME

     bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memmove, memset -- byte string operations

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.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);

     void *
     memchr(const void *b, int c, size_t len);

     int
     memcmp(const void *b1, const void *b2, size_t len);

     void *
     memccpy(void *dst, const void *src, int c, size_t len);

     void *
     memcpy(void *dst, const void *src, size_t len);

     void *
     memmove(void *dst, const void *src, size_t len);

     void *
     memset(void *b, int c, size_t len);

DESCRIPTION

     These functions operate on variable length strings of bytes.  They do not check for terminating null bytes as the routines listed in
     string(3) do.

     See the specific manual pages for more information.

SEE ALSO

     bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3)

STANDARDS

     The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ISO/IEC 9899:1990 (``ISO C90'').

HISTORY

     The functions bzero() and memccpy() appeared in 4.3BSD; the functions bcmp(), bcopy(), appeared in 4.2BSD.
