getmntinfo3
Get information about mounted file systems
Usage
#include <sys/param.h>
#include <sys/ucred.h>
#include <sys/mount.h>
int
getmntinfo(struct statfs **mntbufp, int mode);
Library
Standard C Library (libc, -lc)
Overview
The getmntinfo() function returns an array of statfs() structures describing each currently mounted file system (see statfs(2)).
The getmntinfo() function passes its mode argument transparently to getfsstat(2).
Return values
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.
Errors
The getmntinfo() function may fail and set errno for any of the errors specified for the library routines getfsstat(2) or malloc(3).
