NAME

       strncat - Append a length-limited, NUL-terminated string to another

SYNOPSIS

       char * strncat(char * dest, const char * src, size_t count);

ARGUMENTS

       dest
	   The string to be appended to

       src
	   The string to append to it

       count
	   The maximum numbers of bytes to copy

DESCRIPTION

       Note that in contrast to strncpy, strncat ensures the result is terminated.

NAME

       strcat, strncat - concatenate two strings

SYNOPSIS

       #include <string.h>

       char *strcat(char *dest, const char *src);

       char *strncat(char *dest, const char *src, size_t n);

DESCRIPTION

       The  strcat() function appends the src string to the dest string, overwriting the null byte ('') at the end of dest, and then adds a ter-
       minating null byte.  The strings may not overlap, and the dest string must have enough space for the result.

       The strncat() function is similar, except that

       *  it will use at most n characters from src; and

       *  src does not need to be null-terminated if it contains n or more characters.

       As with strcat(), the resulting string in dest is always null-terminated.

       If src contains n or more characters, strncat() writes n+1 characters to dest (n from src plus the terminating null byte).  Therefore,  the
       size of dest must be at least strlen(dest)+n+1.

       A simple implementation of strncat() might be:

	   char*
	   strncat(char *dest, const char *src, size_t n)
	   {
	       size_t dest_len = strlen(dest);
	       size_t i;

	       for (i = 0 ; i < n && src[i] != '' ; i++)
		   dest[dest_len + i] = src[i];
	       dest[dest_len + i] = '';

	       return dest;
	   }

RETURN VALUE

       The strcat() and strncat() functions return a pointer to the resulting string dest.
