Memory 
 
 
 
Memory allocation and debugging functions. 
 
 
 
 
This set of functions is semantically similar functions to standard C 
library memory allocation routines.  When memory debugging is enabled 
these functions include support to detect buffer overruns.  When 
memory debugging is not enabled the allocation and free calls are 
wrappers around the standard C allocation routines, and checking 
routines are null ops. 
 
 
 
 
Memory debugging is enabled when DEBUG_MEM is defined at compilation 
time.  On Unix systems, the configure script has 
a command-line option --enable-debug-mem.  On Win32, 
a memory debugging is enabled in the debug configuration. 
 
 
 
 
 
 
 
 
 
 
Allocates a block of memory.  Semantically equivalent to malloc(). 
 
 
@x: size of allocation. 
 
 
 
 
Re-sizes a block of memory. Semantically equivalent to realloc(). 
 
 
@p: Pointer to block to be re-dimensioned. 
@x: New size. 
 
 
 
 
xmalloc()'s sufficient memory to store @str, copies @str into it, and 
returns pointer to new string.  Semantically equivalent to strdup(). 
 
 
@str:  
 
@x: String to duplicate.
