buffer_copy(src_buffer, src_offset, size, dest_buffer, dest_offset);
| Argument | Description |
|---|---|
| src_buffer | The index of the buffer to copy from. |
| src_offset | The data offset to start copying from (in bytes). |
| size | The size of the data to copy (in bytes). |
| dest_buffer | The index of the buffer to copy to. |
| dest_offset | The offset position to copy the data to (in bytes). |
Returns: N/A
This function can be used to copy a segment (or all) of the data
stored in one buffer to another. When using two buffers and copying
from one to the other, both buffers must have previously been
created using the buffer_create function (for
example), and you can specify a data offset (in bytes) for the
start point of the data to be copied from the source buffer
relative to the start of the buffer, as well as another data offset
to define the position to copy the data to in the destination
buffer.
NOTE: You cannot copy to the same buffer.
buffer_copy(buff1, 0, 2048, buff2, 2048);
The above code will copy the data stored in the buffer indexed in the variable "buff1", and then paste it into the buffer indexed in the variable "buff2", but offset by 2048 bytes.
