MEMCopy()

Description

MEMCopy() is used to efficiently copy blocks of data from one memory array to another.

Call Signature

void MEMCopy ( any ptr source_ptr, any ptr destination_ptr, int num_bytes )

Return Value

void

This has no return value.

Arguments

any ptr source_ptr:

A pointer to a source memory block. Pointer can be of any type.

any ptr destination_ptr:

A pointer to the destination memory block. Pointer can be of any type.

int num_bytes:

The number of bytes of data to copy.

Example

Copy 10000 bytes starting 5000 bytes into array src to a newly allocated destination buffer (dst).

 local byte ptr src, byte ptr dst

 ...

 dst = EAlloc(byte,10000)

 call MEMCopy(src + 5000, dst, 10000)
