NAME

       m_create_layout - initialize a layout object

SYNOPSIS

       cc [ flag... ] file... -llayout [ library... ]
       #include <sys/layout.h>

       LayoutObject m_create_layout(const AttrObject attrobj,  const char* modifier);

DESCRIPTION

       The m_create_layout() function creates a LayoutObject associated with the locale identified by attrobj.

       The LayoutObject is an opaque object containing all the data and methods necessary to perform the layout operations on context-dependent or
       directional characters of the locale identified by the attrobj. The memory for the LayoutObject is allocated by m_create_layout(). The Lay-
       outObject  created  has	default layout values. If the modifier argument is not NULL, the layout values specified by the modifier overwrite
       the default layout values associated with the locale.  Internal states maintained by the layout transformation function across  transforma-
       tions are set to their initial values.

       The  attrobj argument is or may be an amalgam of many opaque objects. A locale object is just one example of the type of object that can be
       attached to an attribute object. The attrobj argument specifies a name that is usually associated with a locale	category.  If  attrobj	is
       NULL, the created LayoutObject is associated with the current locale as set by the setlocale(3C) function.

       The modifier argument announces a set of layout values when the LayoutObject is created.

RETURN VALUES

       Upon  successful  completion,  the m_create_layout() function returns a LayoutObject for use in subsequent calls to m_*_layout() functions.
       Otherwise the m_create_layout() function returns (LayoutObject) 0 and sets errno to indicate the error.

ERRORS

       The m_create_layout() function may fail if:

       EBADF	       The attribute object is invalid or the locale asssociated with the attribute object is not available.

       EINVAL	       The modifier string has a syntax error or it contains unknown layout values.

       EMFILE	       There are {OPEN_MAX} file descriptors currently open in the calling process.

       ENOMEM	       Insufficient storage space is available.
