array_cats(3)						     Library Functions Manual						     array_cats(3)

NAME

       array_cats - append C string to an array

SYNTAX

       #include <array.h>

       void array_cats(array* x,const char* y);

	 array x;
	 array_cats(&x,"fnord");

DESCRIPTION

       array_cats appends the contents of the 0-terminated string y, not including the terminating 0 byte, to the array x.

       array_cats handles failure in the same way as array_cat.

NAME

       strncat, strncmp, strncpy - Perform operations on string

LIBRARY

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

SYNOPSIS

       #include <string.h>

       char *strncat(
	       char *s1,
	       const char *s2,
	       size_t n);

       int strncmp(
	       const char *s1,
	       const char *s2,
	       size_t n);

       char *strncpy(
	       char *s1,
	       const char *s2,
	       size_t n);

STANDARDS

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

       strncat(), strncmp(), strncpy():  XSH4.2

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

PARAMETERS

       Points  to  a  location	containing  the first string or array.	Points to a location containing the second array.  Specifies the number of
       bytes.  In strncat(), n specifies the maximum number of bytes to append; in strncmp(), n specifies the maximum number of bytes to  compare;
       and in strncpy(), n specifies the number of bytes to copy.

DESCRIPTION

       The strncat() function appends no more than n bytes from the array pointed to by the s2 parameter to the end of the array pointed to by the
       s1 parameter.  The initial byte of the array pointed to by s2 overwrites the null byte at the end of a string pointed to by  s1.   It  then
       appends a null byte to the result, and returns s1.  When operating on overlapping objects, the behavior of this function is unreliable.

       The  strncmp()  function compares the string or array pointed to by the s1 parameter to the array pointed to by the s2 parameter.  The sign
       of a nonzero value returned by strcmp() is determined by the sign of the difference between the values of the first  pair  of  bytes  (both
       interpreted as unsigned char) that differ in the two compared objects. The strncmp() functions compares bytes until it has compared n bytes
       or until it reaches a terminating null byte.

       The strncmp() function compares objects based on the machine collating order. It does not use the locale-dependent sorting order.  Use  the
       strcoll() or wcscoll() functions for locale-dependent sorting.

       The  strncpy() function copies no more than n bytes from the array pointed to by the s2 parameter to the array pointed to by the s1 parame-
       ter.  Bytes following a null byte are not copied.  When operating on overlapping locations, the behavior of this  function  is  unreliable.
       When  the location pointed to by the s2 parameter is an array that is shorter than n bytes, null bytes are appended to the s1 value until n
       bytes in all are written.

RETURN VALUES

       Upon successful completion, the strncat() and strncpy() functions return a pointer to the resulting string or array.  [Tru64  UNIX]  Other-
       wise, these functions return a null pointer.

       Upon successful completion, the strncmp() function returns an integer whose value is greater than, equal to, or less than 0 (zero), accord-
       ing to whether the value of the s1 object is greater than, equal to, or less than the value of the s2 object. [Tru64 UNIX]  When a success-
       ful comparison cannot be made, strncmp() returns a value of 0 (zero).
