-FUNCTION
- <<strcat>>---concatenate strings
-
-INDEX
- strcat
-
-ANSI_SYNOPSIS
- #include <string.h>
- char *strcat(char *<[dst]>, const char *<[src]>);
-
-TRAD_SYNOPSIS
- #include <string.h>
- char *strcat(<[dst]>, <[src]>)
- char *<[dst]>;
- char *<[src]>;
-
-DESCRIPTION
- <<strcat>> appends a copy of the string pointed to by <[src]>
- (including the terminating null character) to the end of the
- string pointed to by <[dst]>. The initial character of
- <[src]> overwrites the null character at the end of <[dst]>.
-
-RETURNS
- This function returns the initial value of <[dst]>
-
-PORTABILITY
-<<strcat>> is ANSI C.
-
-<<strcat>> requires no supporting OS subroutines.
