SYNOPSYS






#include "mut.h"
void *mbkrealloc(pt, bytes)
void *pt;
unsigned int bytes;


PARAMETERS

pt Pointer to an already allocated area, allocated using mbkalloc\P
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;
}
