| 33 | .Sh NAME | |
| 34 | .Nm acl_dup | |
| 35 | .Nd duplicate an ACL | |
| 36 | .Sh LIBRARY | |
| 37 | .Lb libc | |
| 38 | .Sh SYNOPSIS | |
| 39 | .In sys/types.h | |
| 40 | .In sys/acl.h | |
| 41 | .Ft acl_t | |
| 42 | .Fn acl_dup "acl_t acl" | |
| 43 | .Sh DESCRIPTION | |
| 44 | The | |
| 45 | .Fn acl_dup | |
| 46 | function returns a pointer to a copy of the ACL pointed to by the argument | |
| 47 | .Va acl . | |
| 48 | .Pp | |
| 49 | This function may cause memory to be allocated. The caller should free any | |
| 50 | releasable memory, when the new ACL is no longer required, by calling | |
| 51 | .Xr acl_free 3 | |
| 52 | with the | |
| 53 | .Va (void*)acl_t | |
| 54 | as an argument. | |
| 55 | .Pp | |
| 56 | Any existing ACL pointers that refer to the ACL referred to by | |
| 57 | .Va acl | |
| 58 | shall continue to refer to the ACL. | |
| 59 | .Sh RETURN VALUES | |
| 60 | Upon successful completion, this function shall return a pointer to the | |
| 61 | duplicate ACL. Otherwise, a value of | |
| 62 | .Va (acl_t)NULL | |
| 63 | shall be returned, and | |
| 64 | .Va errno | |
| 65 | shall be set to indicate the error. | |
| 66 | .Sh ERRORS | |
| 67 | If any of the following conditions occur, the | |
| 68 | .Fn acl_init | |
| 69 | function shall return a value of | |
| 70 | .Va (acl_t)NULL | |
| 71 | and set | |
| 72 | .Va errno | |
| 73 | to the corresponding value: | |
| 74 | .Bl -tag -width Er | |
| 75 | .It Bq Er EINVAL | |
| 76 | Argument | |
| 77 | .Va acl | |
| 78 | does not point to a valid ACL. | |
| 79 | .It Bq Er ENOMEM | |
| 80 | The | |
| 81 | .Va acl_t | |
| 82 | to be returned requires more memory than is allowed by the hardware or | |
| 83 | system-imposed memory management constraints. | |
