VOLMGT_ROOT(3VOLMGT) Volume Management Library Functions
NAME
volmgt_root - return the volume management root directory
SYNOPSIS
cc [
flag... ]
file...
-lvolmgt [
library ... ]
#include <volmgt.h>
const char *volmgt_root(
void);
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This function is obsolete.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vold, has been replaced by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(7). The return value of this
function is undefined.
The
volmgt_root() function returns the current volume management root
directory, which by default is
/vol but can be configured to be in a
different location.
RETURN VALUES
The return from this function is undefined.
ERRORS
This function may fail if an
open() of
/dev/volctl fails. If this
occurs a pointer to the default Volume Management root directory is
returned.
EXAMPLES
Example 1: Finding the Volume Management Root directory.
To find out where the volume management root directory is:
if ((path = volmgt_root()) != NULL) {
(void) printf("Volume Management root dir=%s\n", path);
} else {
(void) printf("can't find Volume Management root dir\n");
}
FILES
