Struct Buffer 

#[repr(C)]
pub struct Buffer {
    pub ptr: *mut u8,
    pub cap: usize,
    pub len: usize,
}

A caller-provided byte buffer.

APIs that write to this type use len for the number of bytes written on GHOSTTY_SUCCESS and the required byte capacity on GHOSTTY_OUT_OF_SPACE.

Fields

ptr: *mut u8

Destination buffer for bytes. May be NULL when cap is 0 to query required size.

cap: usize

Capacity of ptr in bytes.

len: usize

Bytes written on success, or required byte capacity on GHOSTTY_OUT_OF_SPACE.
