BSTRING(3) Linux Programmer's Manual BSTRING(3) NAME
bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memfrob, memmem, memmove, memset - byte string operations SYNOPSIS
#include <string.h> int bcmp(const void *s1, const void *s2, size_t n); void bcopy(const void *src, void *dest, size_t n); void bzero(void *s, size_t n); void *memccpy(void *dest, const void *src, int c, size_t n); void *memchr(const void *s, int c, size_t n); int memcmp(const void *s1, const void *s2, size_t n); void *memcpy(void *dest, const void *src, size_t n); void *memfrob(void *s, size_t n); void *memmem(const void *needle, size_t needlelen, const void *haystack, size_t haystacklen); void *memmove(void *dest, const void *src, size_t n); void *memset(void *s, int c, size_t n); DESCRIPTION
The byte string functions perform operations on strings (byte arrays) that are not necessarily null-terminated. See the individual man pages for descriptions of each function. NOTES
The functions bcmp(), bcopy() and bzero() are obsolete. Use memcmp(), memcpy() and memset() instead. SEE ALSO

bcopy(3) Library Functions Manual bcopy(3) NAME
bcopy, bcmp, bzero - Perform memory operations LIBRARY
Standard C Library (libc) SYNOPSIS
#include <strings.h> void bcopy( const void *source, void *destination, size_t length); int bcmp( const void *string1, const void *string2, size_t length); void bzero( void *string, size_t length); The following function definitions do not conform to current standards and are supported only for backward compatibility: #include <string.h> void bcopy( const char *source, char *destination, int length); int bcmp( const char *string1, const char *string2, int length); void bzero( char *string, int length); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: bcopy(), bcmp(), bzero(): XSH5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Points to the original string for the bcopy() function. Points to the destination string for the bcopy() function. Specifies the byte string to be compared to the string2 parameter by the bcmp() function. Specifies the byte string to be compared to the string1 parameter by the bcmp() function. Specifies the length (in bytes) of the string. DESCRIPTION
The bcopy(), bcmp(), and bzero() functions operate on variable length strings of bytes. Unlike the string functions, they do not check for null bytes. The bcopy() function copies the value of the length parameter in bytes from the string in the source parameter to the string in the desti- nation parameter. The bcmp() function compares the byte string in the string1 parameter against the byte string of the string2 parameter, returning a 0 (zero) value if the two strings are identical and a nonzero value otherwise. The bzero() function nulls the string in the string parameter, for the value of the length parameter in bytes. NOTES
[Tru64 UNIX] The bcopy() function is similar to the memcpy() function except that the first two parameters are reversed. RELATED INFORMATION
