pos_type tellp();
Which function is used to move file pointer from any position in file in c language?

In an input file what maintains the location of the next item that will be read from the file?
In an input file, the location of the next item to be read is maintained by a file pointer or file cursor. This pointer indicates the current position in the file, allowing the system to know where to read the next byte or block of data. As data is read, the pointer automatically advances to the next position, ensuring sequential access to the file's contents.
What function will read a specified number of elements from a file?
The function fread() in C can be used to read a specified number of elements from a file. It takes as arguments the pointer to the buffer, size of each element, number of elements to read, and the file pointer.
What does the file pointer return?
The file pointer, often used in programming to manage file input and output, returns the current position within a file. It indicates where the next read or write operation will occur. Depending on the context, it can also provide information about the file's end, allowing for efficient data processing and manipulation. Functions or methods associated with file pointers can typically move or adjust this position as needed.
Can a shareable file be opened in a special way so when another process also reads it my process's file pointer is not advanced?
Your process' file pointer has nothing to do with the other process' file pointer.
What is a function to read chars from a certain position to another position in file in C?
Call functions fread, then function fseek, then function fwrite.
Functions used for manipulation of file pointer?

What is a file pointer?
A file pointer is an opaque object that refers to a file. Opaque means that you should not attempt to delve into its specific value, other than to use it as a file pointer. FILE *fp; /* fp is the file pointer */ fp = fopen("somefile.txt"); if (fp == NULL) ...{exception}... fprintf(fp, "Hello somefile.txt"); fclose(fp);
What is the different between header file and header pointer?
Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
