mxRealloc

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.
