fn open3_write(ctx: &i64, data: &i8, len: i64) -> i64Write data to child’s stdin.
open3_read
fn open3_read(ctx: &i64, buf: &i8, max: i64) -> i64Read from child’s stdout.
open3_read_err
fn open3_read_err(ctx: &i64, buf: &i8, max: i64) -> i64Read from child’s stderr.
open3_close_stdin
fn open3_close_stdin(ctx: &i64)Close child’s stdin (signals EOF to child).
open3_wait
fn open3_wait(ctx: &i64) -> i64Wait for child to exit. Returns exit code (0-255) or -1 on error.
open3_capture2
fn open3_capture2(cmd: &i8, argv: &i64, out: &i8, max: i64) -> i64Run command and capture stdout. Returns bytes read.
