VOLMGT_FEATURE_ENABLED(3VOLMGT) Volume Management Library Functions
NAME
volmgt_feature_enabled - check whether specific Volume Management
features are enabled
SYNOPSIS
cc [
flag ... ]
file ...
-l volmgt [
library ... ]
#include <volmgt.h>
int volmgt_feature_enabled(
char *feat_str);
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This function is obsolete.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vold, has been replaced by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_feature_enabled() routine checks whether specific volume
management features are enabled.
volmgt_feature_enabled() checks for
the volume management features passed in to it by the
feat_str parameter.
Currently, the only supported feature string that
volmgt_feature_enabled() checks for is
floppy-summit-interfaces. The
floppy-summit-interfaces feature string checks for the presence of
the
libvolmgt routines
volmgt_acquire() and
volmgt_release().
RETURN VALUES
The return from this function is undefined.
EXAMPLES
Example 1: A sample of the volmgt_feature_enabled() function.
In the following example,
volmgt_feature_enabled() checks whether
the
floppy-summit-interfaces feature is enabled.
if (volmgt_feature_enabled("floppy-summit-interfaces")) {
(void) printf("Media Sharing Routines ARE present\n");
} else {
(void) printf("Media Sharing Routines are NOT present\n");
}
