53 The
54 .Fn memccpy
55 function
56 copies bytes from string
57 .Fa s2
58 to string
59 .Fa s1 .
60 If the character
61 .Fa c
62 (as converted to an unsigned char) occurs in the string
63 .Fa s2 ,
64 the copy stops and a pointer to the byte after the copy of
65 .Fa c
66 in the string
67 .Fa s1
68 is returned.
69 Otherwise,
70 .Fa n
71 bytes are copied, and a NULL pointer is returned.
