.Sh DESCRIPTION
|
|
|
|
|
These functions provide an easy means of manipulating string lists. They are

|
|
|

|
|
|
|
accordingly.
|
|
|
|
|
.Fn rc_stringlist_addu
|
|
|
|
|
only works if

|
|
|

.Fa item
|
|
|
|
|
from

retuning true on success, otherwise false.

|
according to C locale.

|
|
|
|
