* Name: fstatvfs
|
|
*
|
|
* Description:
|
|
* The fstatvfs() function shall obtain information about the file system
|
|
* containing the file referenced by fd.
|
|
*
|
|
* the buf argument is a pointer to a statvfs structure that shall be
|
|
* filled. Read, write, or execute permission of the named file is not
|
|
* required.
|
|
*
|
|
* Returned Value:
|
|
* Upon successful completion, statvfs() shall return 0. Otherwise, it
