【调试方法】C代码中dump中间数据的方法

一，简介

本文主要介绍，如何在C语言代码中将音频流数据进行写入文件，方便调试定位问题：

二，函数实现

按int8_t写入

#include <stdio.h>int32_t write_int8_t_data(int8_t *name, int8_t *buffer, int32_t data_len)
{FILE *fp = NULL;fp = fopen(name, "ab");if(fp == NULL){printf("fopen %s failed!\n", name);return -1;}fwrite(buffer, sizeof(int8_t), data_len, fp);fclose(fp);return 0;
}

按int16_t写入：

int32_t write_int16_t_data(int8_t *name, int16_t *buffer, int32_t data_len)
{FILE *fp = NULL;fp = fopen(name, "ab");if(fp == NULL){printf("fopen %s failed!\n", name);return -1;}fwrite(buffer, sizeof(int16_t), data_len, fp);fclose(fp);return 0;
}

按照int32_t写入：

int32_t write_int32_t_data(int8_t *name, int32_t *buffer, int32_t data_len)
{FILE *fp = NULL;fp = fopen(name, "ab");if(fp == NULL){printf("fopen %s failed!\n", name);return -1;}fwrite(buffer, sizeof(int32_t), data_len, fp);fclose(fp);return 0;
}

按照int64_t写入：

int32_t write_int64_t_data(int8_t *name, int32_t *buffer, int32_t data_len)
{FILE *fp = NULL;fp = fopen(name, "ab");if(fp == NULL){printf("fopen %s failed!\n", name);return -1;}fwrite(buffer, sizeof(int64_t), data_len, fp);fclose(fp);return 0;
}
