getmntent(3X) getmntent(3X)
hasmntopt() Scans the mnt_opts field of the
mntent structure mnt for a substring that
matches opt. It returns the address of the substring if a match is found. Otherwise,
the return value takes one of the following default behaviors :
Option String Corresponding Default Behavior
MNTOPT_RW If the mnt_opts does not have the
MNTOPT_RO option,
MNTOPT_RW is returned. Otherwise, NULL is returned.
MNTOPT_SUID If the mnt_opts does not have the
MNTOPT_NOSUID
option, MNTOPT_SUID is returned. Otherwise, NULL is
returned.
MNTOPT_NOQUOTA
If the mnt_opts does not have the MNTOPT_QUOTA
option, MNTOPT_NOQUTOA
is returned. Otherwise, NULL
is returned.
MNTOPT_FG If the mnt_opts does not have the
MNTOPT_BG option and
mnt_type is MNTTYPE_NFS, MNTOPT_FG is returned.
Otherwise, NULL is returned.
MNTOPT_HARD If the mnt_opts does not have the
MNTOPT_SOFT option
and
mnt_type is MNTTYPE_NFS, MNTOPT_HARD is
returned. Otherwise, NULL is returned.
MNTOPT_INTR If the mnt_opts does not have the MNTOPT_NOINTR
option and mnt_type is MNTTYPE_NFS, MNTOPT_INTR
is returned. Otherwise, NULL is returned.
MNTOPT_DEVS If the mnt_opts does not have the MNTOPT_NODEVS
option and mnt_type is MNTTYPE_NFS, MNTOPT_DEVS
is returned. Otherwise, NULL is returned.
If none of the default behaviors occur, NULL is returned.
Note: When the return value is the result of one of the default behaviors ,itisa
pseudo option string, and not a pointer in the
mnt_ops field.
