/** @file:
|
|
* Creates a directory tree set to the specified permissions.
|
|
*
|
|
* The opal_os_create_dirpath() function creates a directory
|
|
* tree, with each directory that is created in the tree having the specified
|
|
* access permissions. Existing directories within the tree are left
|
|
* untouched - however, if they do not permit the user to create a directory
|
|
* within them, the function will return an error condition.
|
|
*
|
|
* If the specified full path name already exists, the
|
|
* opal_os_create_dirpath() function will check to ensure that
|
|
* the final directory in the tree has at least the specified access permission. In other
|
|
* words, if the directory has read-write-execute for all, and the user
|
|
* has requested read-write access for just the user, then the function
|
|
* will consider the directory acceptable. If the minimal permissions are
|
|
* not currently provided, the function will attempt to change the
|
|
* access permissions of the directory to add the specified
|
|
* permissions. The function will return OMPI_ERROR if this cannot
|
|
* be done.
