30 sty 2011 · In C#, arrays cannot be resized dynamically. One approach is to use System.Collections.ArrayList instead of a native array. Another (faster) solution is to re-allocate the array with a different size and to copy the contents of the old array to the new array.
This method allocates a new array with the specified size, copies elements from the old array to the new one, and then replaces the old array with the new one. array must be a one-dimensional array. If array is null, this method creates a new array with the specified size.
realloc returns a pointer to the resized buffer; this pointer value may be different from the original pointer value, so you need to save that return value somewhere. realloc may return NULL if the request cannot be satsified (in which case the original buffer is left in place).
ReAllocHGlobal is one of two memory reallocation API methods in the Marshal class. (Marshal.ReAllocCoTaskMem is the other.) This method exposes the Win32 GlobalReAlloc function from Kernel32.dll. The returned pointer can differ from the original.

21 maj 2023 · A previous call to free or realloc that deallocates a region of memory synchronizes-with a call to any allocation function, including realloc that allocates the same or a part of the same region of memory.
28 maj 2017 · Size of dynamically allocated memory can be changed by using realloc (). As per the C99 standard: void *realloc(void *ptr, size_t size); . realloc deallocates the old object pointed to by ptr and returns a pointer to a new object that has the size specified by size.
