mxRealloc (External Interfaces Reference)

Reallocate memory

Fortran Syntax

integer*4 function mxRealloc(ptr, size)
integer*4 ptr, size

Arguments

ptr
Pointer to a block of memory allocated by mxCalloc, or by a previous call to mxRealloc.

size
New size of allocated memory, in bytes.

Returns

A pointer to the reallocated block of memory on success, and 0 on failure.

Description

mxRealloc reallocates the memory routine for the managed list. If mxRealloc fails to allocate a block, you must free the block since the ANSI definition of realloc states that the block remains allocated. mxRealloc returns 0 in this case, and in subsequent calls to mxRealloc of the form

```
x = mxRealloc(x, size)
```

Note Failure to reallocate memory with mxRealloc can result in memory leaks.
