volmgt_ownspath(3VOLMGT) Volume Management Library Functions volmgt_ownspath(3VOLMGT)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This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-
ware 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 compar-
ing 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
",
path, media_getid(path));
}
}

volmgt_symname(3VOLMGT) Volume Management Library Functions volmgt_symname(3VOLMGT)NAME
volmgt_symname, volmgt_symdev - convert between Volume Management symbolic names, and the devices that correspond to them
SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ]
#include <volmgt.h>
char *volmgt_symname(char *pathname);
char *volmgt_symdev(char *symname);
DESCRIPTION
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-
ware 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.
These two routines compliment each other, translating between Volume Management's symbolic name for a device, called a symname, and the
/dev pathname for that same device.
volmgt_symname() converts a supplied /dev pathname to a symname, Volume Management's idea of that device's symbolic name.
volmgt_symdev() does the opposite conversion, converting between a symname, Volume Management's idea of a device's symbolic name for a vol-
ume, to the /dev pathname for that device.
RETURN VALUES
The return from this function is undefined.
ERRORS
volmgt_symname() can fail, returning a null string pointer, if a stat(2) of the supplied pathname fails, or if 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 trying to convert the supplied pathname to a symname.
volmgt_symdev() can fail if 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 trying to convert the supplied symname to a /dev pathname.
EXAMPLES
Example 1 Testing Floppies
The following tests how many floppies Volume Management currently sees in floppy drives (up to 10):
for (i=0; i < 10; i++) {
(void) sprintf(path, "floppy%d", i);
if (volmgt_symdev(path) != NULL) {
(void) printf("volume %s is in drive %d
",
path, i);
}
}
Example 2 Finding The Symbolic Name
This code finds out what symbolic name (if any) Volume Management has for /dev/rdsk/c0t6d0s2:
if ((nm = volmgt_symname("/dev/rdsk/c0t6d0s2")) == NULL) {
(void) printf("path not managed
");
} else {
(void) printf("path managed as %s
", nm);
}
