Function nstd_sys::core::mem::nstd_core_mem_zero

#[no_mangle]
pub unsafe extern "C" fn nstd_core_mem_zero(
    buf: *mut NSTDByte,
    size: NSTDUInt
)

Available on crate feature nstd_core only.

Zeros out a memory buffer.

Parameters:

• NSTDByte *buf - A pointer to the first byte in the memory buffer.

• NSTDUInt size - The number of bytes to set to 0.

Panics

This operation will panic if size is greater than NSTDInt’s max value.

Safety

The caller must ensure that buf is valid for reads of size contiguous bytes.

Example

use nstd_sys::core::mem::nstd_core_mem_zero;

unsafe {
    let mut buf = [i32::MAX; 10];
    nstd_core_mem_zero(buf.as_mut_ptr().cast(), core::mem::size_of::<i32>() * 10);
    assert!(buf == [0i32; 10]);
}
