LLSEEK(2) | Linux Programmer's Manual | LLSEEK(2) |
NAME¶
_llseek - reposition read/write file offset
SYNOPSIS¶
#include <sys/types.h> #include <unistd.h> int _llseek(unsigned int fd, unsigned long offset_high, unsigned long offset_low, loff_t *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 associated with the file descriptor fd to (offset_high<<32) | offset_low 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 SEEK_SET, SEEK_CUR, or SEEK_END, respectively. It returns the resulting 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¶
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).
