fwrite(synth, sizeof(short), L_FRAME, f_syn);
如何求取f_syn的大小阿？

FILE * fp = fopen(filepath, "r");
if (fp == NULL) ...;

_setmode(_fileno(fp), _O_BINARY);
fseek(fp, 0, SEEK_END);
size_t filesize = (size_t) ftell(fp);
fclose(fp);

FILE * fp = fopen(filepath, "r");
if (fp == NULL) ...;

_setmode(_fileno(fp), _O_BINARY);
这几句话能不能写成FILE * fp = fopen(filepath, "rb");？

使用函数filelength(int handle)就行啦。
