Alloc

See Also: Memory Management Functions, MemSet

Purpose

Allocates a block of memory.

Return Type

Pointer

Syntax

Alloc({iBytesAllocated})

Where:

• {iBytesAllocated} is the number of bytes requested.

What It Does

Alloc returns either a pointer to the allocated memory block or zero (if the memory cannot be allocated). The memory is allocated on the process heap in DataFlex.

Example

Pointer aInfo
Char cByteNeeded
Integer iRetVal

Move (Alloc(cByteNeeded)) to aInfo
Move (MemSet(aInfo, 0, cByteNeeded)) to iRetVal

Notes

• Alloc does not initialize the memory block; you have to do that separately.
