SYNOPSYS¶
#include "mut.h"
void ∗mbkrealloc(pt, bytes)
void ∗pt;
unsigned int bytes;
PARAMETERS¶
- pt
- Pointer to an already allocated area, allocated using
mbkallocP
- bytes
- Number of memory bytes to be contiguously allocated
DESCRIPTION¶
mbkrealloc returns a block of
bytes length, for any purpose. It
increases or decreases the size of the area, and return a pointer to the new
block. It is now a day only an encapsulation of the system
realloc
function, but may evolve to a special allocator in the future. Its use is
strongly encouraged.
- Remark :
- a global variable, long mbkrealloc_stat, updates the number of
allocated bytes, and may be accessed by anyone to see the amount of
allocated memory.
RETURN VALUE¶
mbkrealloc returns a pointer to a
bytes long block.
ERROR¶
"∗∗∗ mbk error ∗∗∗ mbkrealloc
impossible : not enough memory"
System break can't be moved anymore, no more memory can
be retrieved from the system.
EXAMPLE¶
#include "mut.h"
char ∗concatstring(t, s);
{
t = (char ∗)mbkrealloc(strlen(t) + strlen(s) + 1);
strcat(t, s);
return t;
}
