fea681da | 53 | .SH DESCRIPTION |
60a90ecd MK |
54 | The |
55 | .BR stpcpy () | |
56 | function copies the string pointed to by \fIsrc\fP | |
f81fb444 | 57 | (including the terminating \(aq\\0\(aq character) to the array pointed to by |
1c44bd5b MK |
58 | \fIdest\fP. |
59 | The strings may not overlap, and the destination string | |
fea681da MK |
60 | \fIdest\fP must be large enough to receive the copy. |
61 | .SH "RETURN VALUE" | |
60a90ecd MK |
62 | .BR stpcpy () |
63 | returns a pointer to the \fBend\fP of the string | |
28d88c17 | 64 | \fIdest\fP (that is, the address of the terminating null byte) |
fea681da | 65 | rather than the beginning. |
2b2581ee MK |
66 | .SH "CONFORMING TO" |
67 | This function is not part of the C or POSIX.1 standards, and is | |
008f1ecc | 68 | not customary on UNIX systems, but is not a GNU invention either. |
2b2581ee | 69 | Perhaps it comes from MS-DOS. |
822002bd | 70 | Nowadays, it is also present on the BSDs. |
fea681da | 71 | .SH EXAMPLE |
60a90ecd MK |
72 | For example, this program uses |
73 | .BR stpcpy () | |
74 | to concatenate \fBfoo\fP and | |
fea681da | 75 | \fBbar\fP to produce \fBfoobar\fP, which it then prints. |
