    NAME

    
    
    getmntinfo
    
     - get information about mounted file systems
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <sys/param.h>
       #include <sys/ucred.h>
       #include <sys/mount.h>
    int getmntinfo (struct statfs **mntbufp int flags);
     

    DESCRIPTION

    The getmntinfo ();
    function returns an array of statfs ();
    structures describing each currently mounted file system (see statfs(2)).

    The getmntinfo ();
    function passes its Fa flags 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 Fa mntbufp .

    If an error occurs, zero is returned and the external variable errno is set to indicate the error. Although the pointer Fa 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).  

    SEE ALSO

    getfsstat(2), mount(2), statfs(2), mount(8)  

    HISTORY

    The getmntinfo ();
    function first appeared in BSD 4.4  

    BUGS

    The getmntinfo ();
    function writes the array of structures to an internal static object and returns a pointer to that object. Subsequent calls to getmntinfo ();
    will modify the same object.

    The memory allocated by getmntinfo ();
    cannot be free(3)Ns'd by the application.
