@(#)getmntinfo.3 6.4 (Berkeley) 11/19/90

C 7 getmntinfo - get information about mounted file systems

#include <sys/types.h>
#include <sys/mount.h>

int getmntinfo(mntbufp, flags)
struct statfs **mntbufp;
int flags

Getmntinfo returns an array of statfs structures describing each currently mounted file system (see statfs (2)).

Getmntinfo passes its flags parameter transparently to getfsstat (2).

On successful completion, getmntinfo returns a count of the number of elements in the array. The pointer to the array is stored into mntbufp .

If an error occurs, zero is returned and the external variable errno is set to indicate the error. Although the pointer mntbufp will be unmodified, any information previously returned by getmntinfo will be lost.

All information is contained in a static area, so it must be copied if it is to be saved.

The memory allocated by getmntinfo cannot be free 'd by the application.

Getmntinfo may fail and set errno for any of the errors specified for the library routines getfsstat (2) or malloc (3). getfsstat(2), statfs(2), mount(2), mount(8)
