# XVaCreateNestedList(3)

allocate a nested variable argument list

## NAME

XVaCreateNestedList - allocate a nested variable argument list

## SYNTAX

typedef void \* XVaNestedList;

XVaNestedList XVaCreateNestedList(int *dummy*, ...);

## ARGUMENTS

- *dummy*

  Specifies an unused argument (required by ANSI C).

- ...

  Specifies the variable length argument list.

## DESCRIPTION

The **XVaCreateNestedList** function allocates memory and copies its arguments into a single list pointer, which may be used as a value for arguments requiring a list value. Any entries are copied as specified. Data passed by reference is not copied; the caller must ensure data remains valid for the lifetime of the nested list. The list should be freed using **XFree** when it is no longer needed.
