NAME
mnttab - mounted file system table
SYNOPSIS
#include < mntta.b.h >
DESCRIPTION
Mnttab resides in directory fete and contains a table of devices,
mounted by the mount(1M) command, in the following structure
as defined by < mnttab.h >:
struct mnttab {
char
};
char
short
time_t
mt_dev[lO];
mt_filsys[10];
mt_ro_fig;
mt_time;
Each entry is 26 bytes in length; the first 10 bytes are the nullpadded
name of the place where the special file is mounted; the
next 10 bytes represent the null-padded root name of the mounted
special file; the remaining 6 bytes contain the mounted special
file 's read/write permissions and the date on which it was
mounted.
The maximum number of entries in mnttab is based on the system
parameter NMOUNT located in fusr/src/uts/cf/conf.c, which
defines the number of allowable mounted special files.
