60a90ecd MK |
54 | The |
55 | .BR stpcpy () | |
e4a0d6cb MK |
56 | function copies the string pointed to by |
57 | .I src | |
71d9e7ae | 58 | (including the terminating null byte (\(aq\\0\(aq)) to the array pointed to by |
e4a0d6cb | 59 | .IR dest . |
1c44bd5b | 60 | The strings may not overlap, and the destination string |
e4a0d6cb MK |
61 | .I dest |
62 | must be large enough to receive the copy. | |
47297adb | 63 | .SH RETURN VALUE |
60a90ecd | 64 | .BR stpcpy () |
e4a0d6cb MK |
65 | returns a pointer to the |
66 | .B end | |
67 | of the string | |
68 | .I dest | |
69 | (that is, the address of the terminating null byte) | |
fea681da | 70 | rather than the beginning. |

e3948c69 MK |
84 | This function was added to POSIX.1-2008. |
85 | Before that, it was not part of | |
b35fe3a0 IS |
86 | the C or POSIX.1 standards, nor customary on UNIX systems. |
87 | It first appeared at least as early as 1986, | |
88 | in the Lattice C AmigaDOS compiler, | |
89 | then in the GNU fileutils and GNU textutils in 1989, | |
d6780233 | 90 | and in the GNU C library by 1992. |
4175f999 | 91 | It is also present on the BSDs. |

92 | .SH BUGS |
93 | This function may overrun the buffer | |
94 | .IR dest . | |
fea681da | 95 | .SH EXAMPLE |
60a90ecd MK |
96 | For example, this program uses |
97 | .BR stpcpy () | |
e4a0d6cb MK |
98 | to concatenate |
99 | .B foo | |
100 | and | |
101 | .B bar | |
102 | to produce | |
103 | .BR foobar , | |
104 | which it then prints. | |
