ggeettmmooddee, sseettmmooddee - modify mode bits

DDEESSCCRRIIPPTTIIOONN
The ggeettmmooddee() function returns a copy of the file permission bits _m_o_d_e as
altered by the values pointed to by _s_e_t. While only the mode bits are al
tered, other parts of the file mode may be examined.
The sseettmmooddee() function takes an absolute (octal) or symbolic value, as
described in chmod(1), as an argument and returns a pointer to mode val
ues to be supplied to ggeettmmooddee(). Because some of the symbolic values are
relative to the file creation mask, sseettmmooddee() may call umask(2). If this
occurs, the file creation mask will be restored before sseettmmooddee() returns.
If the calling program changes the value of its file creation mask after
calling sseettmmooddee(), sseettmmooddee() must be called again if ggeettmmooddee() is to mod
ify future file modes correctly.
If the mode passed to sseettmmooddee() is invalid, sseettmmooddee() returns NULL.
EERRRROORRSS
The sseettmmooddee() function may fail and set errno for any of the errors spec
ified for the library routine malloc(3).
