52 | The | ||
53 | .Fn wcscpy | ||
54 | and | ||
55 | .Fn wcsncpy | ||
56 | functions copy the wide string | ||
57 | .Fa src | ||
58 | to | ||
59 | .Fa dst | ||
60 | (including the terminating null wide character). | ||
61 | .Pp | ||
62 | The | ||
63 | .Fn wcsncpy | ||
64 | function copies not more than | ||
65 | .Fa len | ||
66 | wide characters to | ||
67 | .Fa dst , | ||
68 | appending null wide characters if the length of | ||
69 | .Fa src | ||
70 | is less than | ||
71 | .Fa len , | ||
72 | and | ||
73 | .Em not | ||
74 | terminating | ||
75 | .Fa dst | ||
76 | if the length of | ||
77 | .Fa src | ||
78 | is greater than or equal to | ||
79 | .Fa len . | ||
80 | .Pp | ||
81 | If the | ||
82 | .Fa src | ||
83 | and | ||
84 | .Fa dst | ||
85 | strings overlap, the behavior is undefined. | ||

101 | The | ||
102 | .Fn wcscpy | ||
103 | and | ||
104 | .Fn wcsncpy | ||
105 | functions conform to | ||
106 | .St -isoC-99 | ||
107 | and were first introduced in | ||
108 | .St -isoC-amd1 . | ||
109 | .Sh HISTORY | ||
110 | The | ||
111 | .Fn wcscpy | ||
112 | and | ||
113 | .Fn wcsncpy | ||
114 | functions were ported from | ||
115 | .Nx | ||
116 | and first appeared in | ||
117 | .Ox 3.8 . | ||
118 | .Sh CAVEATS | ||
119 | Using the functions | ||
120 | .Fn wcscpy | ||
121 | and | ||
122 | .Fn wcsncpy | ||
123 | is very error-prone with respect to buffer overflows; | ||
124 | see the EXAMPLES section in | ||
125 | .Xr strncpy 3 | ||
126 | for correct usage. | ||
127 | Using | ||
128 | .Xr wcslcpy 3 | ||
129 | is a better choice in most cases. | ||
