.TH VOLMGT_SYMNAME 3VOLMGT "Mar 8, 2007"
.SH NAME
volmgt_symname, volmgt_symdev \- convert between Volume Management symbolic
names, and the devices that correspond to them
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lvolmgt\fR [ \fIlibrary\fR... ]
#include <volmgt.h>
\fBchar *\fR\fBvolmgt_symname\fR(\fBchar *\fR\fIpathname\fR);
.fi
.LP
.nf
\fBchar *\fR\fBvolmgt_symdev\fR(\fBchar *\fR\fIsymname\fR);
.fi
.SH DESCRIPTION
.sp
.LP
This function is obsolete. The management of removable media by the Volume
Management feature, including \fBvold\fR, has been replaced by software that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
\fBhal\fR(5). The return value of this function is undefined.
.sp
.LP
These two routines compliment each other, translating between Volume
Management's symbolic name for a device, called a \fIsymname\fR, and the
\fB/dev\fR \fIpathname\fR for that same device.
.sp
.LP
\fBvolmgt_symname\fR(\|) converts a supplied \fB/dev\fR \fIpathname\fR to a
\fBsymname\fR, Volume Management's idea of that device's symbolic name.
.sp
.LP
\fBvolmgt_symdev\fR(\|) does the opposite conversion, converting between a
\fIsymname\fR, Volume Management's idea of a device's symbolic name for a
volume, to the \fB/dev\fR \fIpathname\fR for that device.
.SH RETURN VALUES
.sp
.LP
The return from this function is undefined.
.SH ERRORS
.sp
.LP
\fBvolmgt_symname\fR(\|) can fail, returning a null string pointer, if a
\fBstat\fR(2) of the supplied \fBpathname\fR fails, or if an \fBopen\fR(2) of
\fB/dev/volctl\fR fails, or if any of the following is true:
.sp
.ne 2
.na
\fB\fBENXIO\fR\fR
.ad
.RS 9n
Volume Management is not running.
.RE
.sp
.ne 2
.na
\fB\fBEINTR\fR\fR
.ad
.RS 9n
An interrupt signal was detected while trying to convert the supplied
\fIpathname\fR to a \fIsymname\fR.
.RE
.sp
.LP
\fBvolmgt_symdev\fR(\|) can fail if an \fBopen\fR(2) of \fB/dev/volctl\fR
fails, or if any of the following is true:
.sp
.ne 2
.na
\fB\fBENXIO\fR\fR
.ad
.RS 9n
Volume Management is not running.
.RE
.sp
.ne 2
.na
\fB\fBEINTR\fR\fR
.ad
.RS 9n
An interrupt signal was detected while trying to convert the supplied
\fIsymname\fR to a \fB/dev\fR \fIpathname\fR.
.RE
.SH EXAMPLES
.LP
\fBExample 1 \fRTesting Floppies
.sp
.LP
The following tests how many floppies Volume Management currently sees in
floppy drives (up to 10):
.sp
.in +2
.nf
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\en",
path, i);
}
}
.fi
.in -2
.LP
\fBExample 2 \fRFinding The Symbolic Name
.sp
.LP
This code finds out what symbolic name (if any) Volume Management has for
\fB/dev/rdsk/c0t6d0s2\fR:
.sp
.in +2
.nf
if ((nm = volmgt_symname("/dev/rdsk/c0t6d0s2")) == NULL) {
(void) printf("path not managed\en");
} else {
(void) printf("path managed as %s\en", nm);
}
.fi
