    NAME

    volmgt_inuse - check whether or not volume management is managing a pathname
     
    

    SYNOPSIS

    cc [ flag ... ] file ... -lvolmgt [ library ... ]
    #include <volmgt.h>
    
    
    
    int volmgt_inuse(char *pathname);
    

     

    DESCRIPTION

    This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by software that supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is through the HAL APIs, which are documented on the HAL web site. See hal(5). The return value of this function is undefined.

    volmgt_inuse() checks whether volume management is managing the specified pathname.  

    RETURN VALUES

    The return from this function is undefined.  

    ERRORS

    This routine can fail, returning 0, if a stat(2) of the supplied pathname or an open(2) of /dev/volctl fails, or if any of the following is true:

    ENXIO

    Volume management is not running.

    EINTR

    An interrupt signal was detected while checking for the supplied pathname for use.

     

    EXAMPLES

    Example 1 Using volmgt_inuse()

    To see if volume management is managing the first floppy disk:

    if (volmgt_inuse("/dev/rdiskette0") != 0) {
           (void) printf("volmgt is managing diskette 0\n");
    } else {
           (void) printf("volmgt is NOT managing diskette 0\n");
    }
    

     

    ATTRIBUTES

    SEE ALSO

    cc(1B), open(2), stat(2), errno(3C), volmgt_check(3VOLMGT), volmgt_running(3VOLMGT), attributes(5), hal(5)  

    NOTES

    This routine requires volume management to be running.

    Since volmgt_inuse() returns 0 for two different cases (both when a volume is not in use, and when an error occurs), it is up to the user to to check errno to differentiate the two, and to ensure that volume management is running.
