XtOffset __libmansuffix__ __xorgversion__ "XT FUNCTIONS"
NAME
XtOffset, XtOffsetOf, XtNumber - determine the byte offset or number of array elements
SYNTAX
#include <X11/Intrinsic.h>
Cardinal XtOffset(Type pointer_type, Field field_name);
Cardinal XtOffsetOf(Type structure_type, Field field_name);
Cardinal XtNumber(ArrayVariable array);
ARGUMENTS
array 1i
Specifies a fixed-size array.
field_name 1i
Specifies the name of the field for which to calculate the byte offset.
pointer_type 1i
Specifies a type that is declared as a pointer to the structure.
structure_type 1i
Specifies a type that is declared as a structure.
DESCRIPTION
The
XtOffset macro is usually used to determine the offset of various resource fields
from the beginning of a widget and can be used at compile time in static
initializations.
The XtOffsetOf macro expands to a constant expression that gives the offset in bytes to the specified structure member from the beginning of the structure. It is normally used to statically initialize resource lists and is more portable than XtOffset , which serves the same function.
The XtNumber macro returns the number of elements in the specified argument lists, resources lists, and other counted arrays.
