找一个C语言创建COMTRADE录波文件中binary格式dat文件的代码示例

以下是一个C语言创建COMTRADE录波文件中binary格式dat文件的代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

float data[MAX_ANALOG_CHANNELS][MAX_DIGITAL_CHANNELS];
} ComtradeData;

void write_comtrade_dat_file(const char* filename, ComtradeData* data) {
FILE* fp = fopen(filename, "wb");
if (fp == NULL) {

}

// Write data

}
}

}
