NAME
llseek - reposition read/write file offset SYNOPSIS
#include
#include
int llseek(unsigned int fd, unsigned long offsethigh, unsigned long offsetlow, lofft *result, unsigned int whence); Note: There is no glibc wrapper for this system call; see NOTES. DESCRIPTION The llseek() function repositions the offset of the open file associ‐ ated with the file descriptor fd to (offsethigh<<32) | offsetlow bytes relative to the beginning of the file, the current position in the file, or the end of the file, depending on whether whence is SEEKSET, SEEKCUR, or SEEKEND, respectively. It returns the result‐ ing file position in the argument result. RETURN VALUE Upon successful completion, llseek() returns 0. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS EBADF fd is not an open file descriptor. EFAULT Problem with copying results to user space. EINVAL whence is invalid. CONFORMING TO
This function is Linux-specific, and should not be used in programs intended to be portable. NOTES Glibc does not provide a wrapper for this system call; call it using syscall(2). SEE ALSO lseek(2), lseek64(3) COLOPHON
