Native.getBytes介绍

[英]Return a byte array corresponding to the given String. If the system property jna.encoding is set, its value will override the default platform encoding (if supported).
[中]返回与给定字符串对应的字节数组。如果设置了系统属性jna.encoding,其值将覆盖默认的平台编码(如果支持)。

/**
 * @param s The string. Must not be {@code null}.
 * @param charset The charset used to encode {@code s}. Must not be {@code null}.
 * @return A NUL-terminated byte buffer equivalent to the given String,
 * using the given charset.
 * @see #getBytes(String, String)
