/*	PROGRAM'S INTERFACE TO MEMORY ALLOCATION ROUTINES		*/

/*	This file serves as the interface between the program and the
	memory allocating routines.
	There are 3 memory allocation routines:
		char *Malloc(n)		allocate n bytes
		char *Salloc(str, n)	allocate n bytes and fill them with
					string str
		char *Realloc(str, n)	reallocate the string at str to n bytes,
					only works if str was last allocated
*/

extern char *Salloc(), *Malloc(), *Srealloc();
extern char *malloc(), *realloc();
