* ANSI_SYNOPSIS
|
|
sl@0
|
20 |
* #include <string.h>
|
|
sl@0
|
21 |
* char *strncat(char *<[dst]>, const char *<[src]>, size_t <[length]>);

22 |
* TRAD_SYNOPSIS
|
|
sl@0
|
23 |
* #include <string.h>
|
|
sl@0
|
24 |
* char *strncat(<[dst]>, <[src]>, <[length]>)
|
|
sl@0
|
25 |
* char *<[dst]>;
|
|
sl@0
|
26 |
* char *<[src]>;
|
|
sl@0
|
27 |
* size_t <[length]>;
|
|
sl@0
|
28 |
* <<strncat>> appends not more than <[length]> characters from
|
|
sl@0
|
29 |
* the string pointed to by <[src]> (including the terminating
|
|
sl@0
|
30 |
* null character) to the end of the string pointed to by
|
|
sl@0
|
31 |
* <[dst]>. The initial character of <[src]> overwrites the null
|
|
sl@0
|
32 |
* character at the end of <[dst]>. A terminating null character
|
|
sl@0
|
33 |
* is always appended to the result
|
|
sl@0
|
34 |
* WARNINGS
|
|
sl@0
|
35 |
* Note that a null is always appended, so that if the copy is
|
|
sl@0
|
36 |
* limited by the <[length]> argument, the number of characters
|
|
sl@0
|
37 |
* appended to <[dst]> is <<n + 1>>.
|
|
sl@0
|
38 |
* RETURNS
|
|
sl@0
|
39 |
* This function returns the initial value of <[dst]>
|
|
sl@0
|
40 |
* PORTABILITY
|
|
sl@0
|
41 |
* <<strncat>> is ANSI C.
|
|
sl@0
|
42 |
* <<strncat>> requires no supporting OS subroutines.

/**
|

sl@0
|
54 |
Append substring to string.
|
|
sl@0
|
55 |
Appends num characters of src string to dest string.
|
|
sl@0
|
56 |
If the terminating null-character appears in src string
|
|
sl@0
|
57 |
before num character have been appended, the function appends
|
|
sl@0
|
58 |
the null-character to dest and ends.
|
|
sl@0
|
59 |
The terminating null character in dest is overwritten by the first character of src.
|
|
sl@0
|
60 |
The resulting string includes a null-character at end.
|
|
sl@0
|
61 |
@return s1 is returned
|
|
sl@0
|
62 |
@param s1 Pointer to a null-terminated string with enough space allocated to contain src
|
|
sl@0
|
63 |
plus num characters.
|
|
sl@0
|
64 |
@param s2 Null-terminated string containing characters to be appended.
|
|
sl@0
