A file is a collection of related data stored on a disk. C supports a wide range of functions that have the ability to perform basic file operations, which include: Naming a file Opening a file Reading data from
_IO_file_fopen ((FILE *) new_f, filename, mode, is32) 注意:上面的函数调用过程中将new_f指针从locked_FILE转为了FILE,这样做是合法的,因为locked_FILE中第一个变量_IO_FILE_plus的首个变量即是FILE,实际上这样做使得new_f指针的访问被截断,只能访问前面FILE中的内容。 //glibc/libio/...

As of 0.6.1, the name is _file_identifier to reduce the risk of conflicts. The old form is deprecated but still generated for tables without a field named 'identifier' for backwards compatibility. Mostly this macro is used for higher level functions such as mytable_create_as_root which nee...

On Windows, use the MSVC++ sln file in the msvc/picoc folder. Porting PicoC platform.h is where you select your platform type and specify the includes etc. for your platform. platform_XXX.c contains support functions so the compiler can work on your platform, such as how to write charac...
You want to split your code into separate functions, as having everything in one function and in one implementation file is bad practice because it gets difficult to read and to debug the code. Problem The function parts you want to split are not independent from one another. As usual in ...
There are two void functions: CreateFiles() and ShowRecord(int recnum). CreateFiles uses a char * buffer of size 1100 to hold a temporary string made up of the format string msg followed by n asterisks where n varies from 5 to 1004. Two FILE * are created both using wb filemode in ...
