What do you mean by "HP"?  If that's Hewlett-Packard, you need to specify the machine/operating system.  HP makes MANY different computer systems and has several different operating systems including Windows on their systems.

Use 'statfs()':

NAME
       statfs, fstatfs - get file system statistics

SYNOPSIS
       #include <sys/vfs.h>

       int statfs(const char *path, struct statfs *buf);
       int fstatfs(int fd, struct statfs *buf);

DESCRIPTION
       statfs  returns  information  about a mounted file system.
       path is the path name  of  any  file  within  the  mounted
       filesystem.   buf  is  a  pointer  to  a  statfs structure
       defined as follows:

              struct statfs {
                 long    f_type;     /* type of filesystem (see below) */
                 long    f_bsize;    /* optimal transfer block size */
                 long    f_blocks;   /* total data blocks in file system */
                 long    f_bfree;    /* free blocks in fs */
                 long    f_bavail;   /* free blocks avail to non-superuser */
                 long    f_files;    /* total file nodes in file system */
                 long    f_ffree;    /* free file nodes in fs */
                 fsid_t  f_fsid;     /* file system id */
                 long    f_namelen;  /* maximum length of filenames */
                 long    f_spare[6]; /* spare for later */
              };
