转换:
void printIOBufDesc_io(sTIDL_IOBufDesc_t* ioBufDesc) {
FILE *file = fopen("/opt/NetBuf_struct.c", "w");
if (file == NULL) {
printf("printIOBufDescAll() : Error opening file!\n");
return;
}
// 保存为能够直接在代码里赋值的语句
fprintf(file, "static unsigned char binData\[\] = {");
for (int i = 0; i < sizeof(sTIDL_IOBufDesc_t); i++) {
if (i % 16 == 0) {
fprintf(file, "\n ");
}
fprintf(file, "0x%02X", ((unsigned char *)ioBufDesc)i);
if (i != sizeof(sTIDL_IOBufDesc_t) - 1) {
fprintf(file, ", ");
}
}
fprintf(file, "\n};\n");
fclose(file);
}
数组使用:
memcpy(ioBufDesc, binData, sizeof(sTIDL_IOBufDesc_t));
