How to align a local variable at word-aligned address

Hi

Does anyone know how to force a local variable to be aligned at word address?
The DMA transfer needs word-aligned address.
Thanks.

#define WORD_NUM  1
char MyLocal[WORD_NUM*sizeof(short)+1];
short *p=(short *)MyLocal;
p&=(long )~1;//word boundary.
