Synopsys

#include mutnnn.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 mutnnn.h"
char *concatstring(t, s);
{
t = (char *)mbkrealloc(strlen(t) + strlen(s) + 1); strcat(t, s); return t;
}
