将uint32 从little endian转换为char数组（写入文件）

Posted 2021-02-23

Do you know how to convert uint32_t in little endian to file like char array? I have a variable sumGlobalContentSum (in hex). Than i write in file dstFile. Value of sumGlobalContentSum is realy d1 when I write it out like cout

uint32_t sumGlobalContentSum = ;
 
sumGlobalContentSum = 4+2+4+audioDataContentSumNonUsed+4 //=d1 [uint32_t audioDataContentSumNonUsed]
 
dstFile << hex << sumGlobalContentSum;
