The lseek() system call is actually of the following form
lseek(file_name, offset, whence)
file_name is the name of the file
offset is amount the file pointer should move
whence is the way in which offset should be referenced
whence can be SEEK_SET, SEEK_CUR, SEEK_END
Now we have to move 50 bytes from the beginning of the file
Assuming that file is opened for the first time, the file cursor is present at the beginning of the file
The system call would be :
lseek(file_name, 50, SEEK_SET)
Add Answer to:
Use a system call Iseek() to move a file pointer to 50 bytes after the beginning...

Question 12 Consider a magnetic disk drive with 10 double sided platters, 512(=2^9) tracks per surface, and 1024 (=2^10) sectors per track. Sector size is 2KBytes (=2^10 Bytes ). Assume the average seek time 0.02 ms, the seek time from a track to its adjacent track can be ignored. The drive rotates at 5400 rpm. Successive tracks in a cylinder can be read without head movement. Furthermore, disks can be handled independently, so multiple tracks in a cylinder can be...

In Unix/Linux, input and output are treated as files and referenced by the operating system using file descriptors. When you open a shell session, for example, three file descriptors are in use: 0 standard input (stdin) 1 standard output (stdout) 2 standard error (stderr) By default, the command interpreter (shell) reads keyboard input from file descriptor 0 (stdin) and writes output to file descriptor 1 (stdout), which appears on the screen. As you explored in Lab 2, input/output can be...

Write a c++ program in that file to perform a “Search and Replace All” operation. This operation consists of performing a case-sensitive search for all occurrences of an arbitrary sequence of characters within a file and substituting another arbitrary sequence in place of them. Please note: One of the biggest problems some students have with this exercise occurs simply because they don’t read the command line information in the course document titled “Using the Compiler’s IDE”. Your program: 1. must...

Consider an allocator on a 32-bit system that uses an implicit free list. Each memory block, either allocated or free, has a size that is a multiple of four bytes. Thus, only the 30 higher order bits in the header and footer are needed to record block size, which includes the header and footer and is represented in units of bytes. The usage of the remaining 2 lower order bits is as follows: bit 0 indicates the use of the...
