Bionic API与原生线程开发指南

1. Bionic API基础

1.1 流数据读取

1.1.1 读取换行符终止的字符序列

可以使用 fgets 函数从流中读取换行符终止的字符序列。示例代码如下：

char buffer[1024];
/* Read newline terminated character sequence from the stream. */
if (NULL == fgets(buffer, 1024, stream))
{
    /* Error occured while reading the stream. */
}
else
{
    MY_LOG_INFO("read: %s", buffer);
}

成功时返回缓冲区指针，否则返回 NULL 指针。

1.1.2 读取单个字符

使用 fgetc 函数从流中读取单个无符号字符，示例代码如下：

unsigned char ch;
int result;
/* Read a single character from the stream. */
result = fgetc(stream);
if (EOF == result)
{
    /* Error occured while reading from the stream. */
}
else
{
    /*
