m_setvalues_layout(3LAYOUT)				 Layout Service Library Functions			       m_setvalues_layout(3LAYOUT)

NAME

       m_setvalues_layout - set layout values of a LayoutObject

SYNOPSIS

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

       int m_setvalues_layout(LayoutObject layout_object, const LayoutValues values, int *index_returned);

DESCRIPTION

       The m_setvalues_layout() function changes the layout values of a LayoutObject.

       The layout_object argument specifies a LayoutObject returned by the m_create_layout(3LAYOUT) function.

       The values argument specifies the list of layout values that are to be changed. The values are written into the LayoutObject and may affect
       the behavior of subsequent layout functions.  Some layout values do alter internal states maintained by a LayoutObject.

       The m_setvalues_layout() function can be implemented as a macro that evaluates the first argument twice.

RETURN VALUES

       Upon successful completion, the requested layout values are set and 0 is returned. Otherwise -1 is returned and errno is  set  to  indicate
       the  error.  If	any  value  cannot be set, none of the layout values are changed and the (zero-based) index of the first value causing the
       error is returned in index_returned.

ERRORS

       The m_setvalues_layout() function may fail if:

       EINVAL	       The layout value specified by index_returned is unknown, its value is invalid, or the layout_object argument is invalid.

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

USAGE

       Do not use expressions with side effects such as auto-increment or auto-decrement within the first  argument  to  the  m_setvalues_layout()
       function.
