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.

strspn(3)						     Library Functions Manual							 strspn(3)

NAME

       strcspn, strspn - Returns length of initial segment of string

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <string.h>

       size_t strcspn(
	       const char *s1,
	       const char *s2);

       size_t strspn(
	       const char *s1,
	       const char *s2);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       strcspn(), strspn():  XSH4.2

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points  to  a  character string being checked for an initial segment.  Points to a string containing a set of bytes that define the initial
       segment.

DESCRIPTION

       The strspn() function computes the length of the maximum initial segment of the string pointed to  by  the  s1  parameter,  which  consists
       entirely of bytes from the string pointed to by the s2 parameter.

       The strcspn() function computes the byte length of the maximum initial segment of the string pointed to by the s1 parameter, which consists
       entirely of bytes that are not from the string pointed to by the s2 parameter.

       The strspn() and strcspn() functions treat the s2 parameter as a series of bytes; these functions do not treat a multibyte character  as  a
       single  unit  but rather as a series of separate bytes. There are no equivalent functions for multibyte character strings. The wcsspn() and
       wcscspn() functions provide the same functionality for wide character strings.

RETURN VALUES

       Upon successful completion, the strcspn(), and strspn() functions return the length of the string segment.

       [Tru64 UNIX]  On error, a value of -1 cast to size_t is returned.
