NAME

volmgt_ownspath - check volume management name space for path

SYNOPSIS

cc [flag]... file... -lvolgmt [library]...
#include <volmgt.h>

int volmgt_ownspath(char *path);

PARAMETERS

path

: A string containing the path.

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This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by software that supports the Hardware Abstraction Layer (HAL).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.

The volmgt_ownspath() function checks to see if a given path is contained in the volume management name space. This is achieved by comparing the beginning of the supplied path name with the output from volmgt_root(3VOLMGT)

RETURN VALUES

The return from this function is undefined.

EXAMPLES

Example 1 Using volmgt_ownspath()

The following example first checks if volume management is running, then checks the volume management name space for path, and then returns the id for the piece of media.

char *path;

...

if (volmgt_running()) {
    if (volmgt_ownspath(path)) {
         (void) printf("id of %s is %lld\n",
              path, media_getid(path));
    }
}
