* Name: mkdtemp
|

|
*
|
||
|
|
* Description:
|
||
|
|
* The mkdtemp() function shall create a directory with a unique name
|
||
|
|
* derived from template. The application shall ensure that the string
|
||
|
|
* provided in template is a pathname ending with at least six trailing
|
||
|
|
* 'X' characters. The mkdtemp() function shall modify the contents of
|
||
|
|
* template by replacing six or more 'X' characters at the end of the
|
||
|
|
* pathname with the same number of characters from the portable filename
|
||
|
|
* character set. The characters shall be chosen such that the resulting
|
||
|
|
* pathname does not duplicate the name of an existing file at the time
|
||
|
|
* of the call to mkdtemp(). The mkdtemp() function shall use the
|
||
|
|
* resulting pathname to create the new directory as if by a call to:
|
||
|
|
*
|
||
|
|
* Input Parameters:
|
||
|
|
* template - The base directory name that will be modified to produce
|
||
|
|
* the unique name. This must be a full path beginning with /tmp.
|
||
|
|
* This function will modify only the first XXXXXX characters within
|
||
|
|
* that full path.
|
||
|
|
*
|
||
|
|
* Returned Value:
|
||
|
|
* Upon successful completion, the mkdtemp() function shall return the
|
||
|
|
* value of template. Otherwise, it shall return a null pointer and
|
||
|
|
* shall set errno to indicate the error.
