Function nstd_core_mem_copy 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_core_mem_copy(
    dest: *mut NSTDByte,
    src: *const NSTDByte,
    num: NSTDUInt,
)

Available on crate feature core only.

Copies num bytes from src to dest.

Parameters:

• NSTDByte *dest - A pointer to the memory buffer to copy src’s bytes to.

• const NSTDByte *src - A pointer to the memory buffer to copy from.

• NSTDUInt num - The number of bytes to copy from src to dest.

Safety

This function is highly unsafe as it does not know how large either of the memory buffers are, quickly leading to undefined behavior if this function ends up reading or writing past the end of a buffer.

Example

use nstd_sys::core::mem::nstd_core_mem_copy;

unsafe {
    let buf1 = [0u8; 25];
    let mut buf2 = [u8::MAX; 25];
    nstd_core_mem_copy(buf2.as_mut_ptr(), buf1.as_ptr(), 25);
    assert!(buf1 == buf2);
}
