The g

\btm
\bmn
\bnt
\bti
\bin

\bfo
\bo() function returns an array of statfs structures describ-
ing each currently mounted file system (see statfs(2)).
The g
\bge

\bti

\bfo
\bo() function passes its _

On successful completion, g
\bge
\bet
\btm
\bmn
\bnt
\bti

\bnf
\bfo
\bo() returns a count of the number of
elements in the array. The pointer to the array is stored into _
\bm_
\bn_
\bt_
\bb_
\bu_
\bf_
\bp.
If an error occurs, zero is returned and the external variable _
\be_
\br_
\br_
\bn_
\bo is
set to indicate the error. Although the pointer _
\bm_
\bn_
\bt_
\bb_
\bu_
\bf_
\bp will be unmodi-
fied, any information previously returned by g
\bge
\bet

\bfo
\bo() will be lost.
The g

\bfo
\bo() function may fail and set errno for any of the errors
specified for the library routines getfsstat(2) or malloc(3).

The g

\bfo
\bo() function first appeared in 4.4BSD.
The g
\bge
\bet
\btm
\bmn
\bnt
\bti
\bin
\bnf
\bfo
\bo() function writes the array of structures to an internal
static object and returns a pointer to that object. Subsequent calls to
g
\bge
\bet
\btm
\bmn
\bnt
\bti
\bin
\bnf
\bfo
\bo() will modify the same object.
The memory allocated by g

\bo() cannot be free(2)'d by the applica-
projects / unix-history / blob
