READLABELFS(3)             BSD Programmer's Manual              READLABELFS(3)

NAME

     readlabelfs - read disklabel filesystem type

SYNOPSIS

     #include <util.h>

     const char *
     readlabelfs(const char *device, int verbose);

DESCRIPTION

     The readlabelfs() function attempts to determine the filesystem type of
     the disk partition specified by device and returns it in a short form
     that can be easily used to construct arguments within mount(8) and simi-
     lar high-level filesystem utilities.

     If the verbose argument is not 0, readlabelfs() will print appropriate
     error messages before returning. Otherwise, it produces no output on the
     terminal.

RETURN VALUES

     readlabelfs() returns NULL upon error, or a valid filesystem type upon
     success.

HISTORY

     readlabelfs() first appeared in OpenBSD 2.0. The two const qualifiers
     were added in MirBSD #11.
