.SH DESCRIPTION
|
||
|
|
.I Mktemp
|
||
|
|
replaces
|
||
|
|
.I template
|
||
|
|
by a unique file name, and returns the
|
||
|
|
address of the template.
|
||
|
|
The template should look like a file name with eleven trailing
|
||
|
|
.LR X s.
|
||
|
|
The
|
||

|
.LR X s

|
||
|
|
Letters from
|
||
|
|
.L a
|
||
|
|
to
|
||
|
|
.L z

|
are tried until a name that can be accessed
|
||
|
|
(see
|
||
|
|
.IR access (2))
|
||
|
|
is generated.
|
||
|
|

|
||
|
|
.I mktemp
|
||
|
|
returns
