std::path 사용법

할당 없이 경로를 분석/복사합니다.

import

import("std::path::core");
import("std::path::analyze");
import("std::path::copy");

1. 경로 결합

fun main() {
    var out: array<u8, 256>;
    var n: i32 = path_join2(&out[0], 256, "/var/log", "wave/app.log");

    if (n < 0) {
        // 버퍼 부족
    }
}

2. basename / dirname 추출

fun main() {
    var base: array<u8, 64>;
    var dir: array<u8, 128>;

    path_basename_copy(&base[0], 64, "/tmp/data/report.txt"); // report.txt
    path_dirname_copy(&dir[0], 128, "/tmp/data/report.txt"); // /tmp/data
}

3. 분석 함수

fun main() {
    var abs: bool = path_is_abs("/usr/bin");
    var has_ext: bool = path_has_ext("main.wave");
    var ext_pos: i32 = path_ext_start("main.wave");
}
