malloc 与 uint8_t 之间的区别
这里是C语言新手。我不确定通过 malloc 向文件分配内存和执行操作之间的区别。
typedef uint8_t BYTE;
BYTE filename[//number of bytes]
例如,读取文件的开头并检查 jpeg,我们使用后者来检查其“签名”的前 4 个字节。这涉及到“fread”函数,以便读取前 4 个字节并将其临时存储在称为文件名的地方。我不会对 malloc 做同样的事情吗?不确定两者之间的确切区别是什么。
提前感谢大家回答我的问题!
newbie to C language here. I am not sure of the difference between allocating memory to a file through malloc, and doing
typedef uint8_t BYTE;
BYTE filename[//number of bytes]
For instance reading the start of a file and checking for jpeg, we are using the latter to check for the first 4 bytes for its "signature". This involves "fread" function in order to read the first 4 bytes and temporarily store it in this place called filename. Won't I be doing the same thing with malloc? Not sure what is the exact difference between the 2.
Thanks everyone in advance for answering my question!
