.sh description |
the |
.br mkdtemp () |
function generates a uniquely named temporary |
directory from \fitemplate\fp. |
the last six characters of \fitemplate\fp |
must be xxxxxx and these are replaced with a string that makes the |
directory name unique. |
the directory is then created with |
permissions 0700. |
since it will be modified, |
.i template |
must not be a string constant, but should be declared as a character array. |
.sh return value |
the |
.br mkdtemp () |
function returns a pointer to the modified template |
string on success, and null on failure, in which case |
.i errno |
is set to indicate the error. |
.sh errors |
.tp |
.b einval |
the last six characters of \fitemplate\fp were not xxxxxx. |
now \fitemplate\fp is unchanged. |
.pp |
also see |
.br mkdir (2) |
for other possible values for \fierrno\fp. |
