-ANSI_SYNOPSIS
- #include <unistd.h>
- ssize_t pwrite(int <[fd]>, const void *<[buf]>,
- size_t <[n]>, off_t <[off]>);
- ssize_t _pwrite_r(struct _reent *<[rptr]>, int <[fd]>,
- const void *<[buf]>, size_t <[n]>, off_t <[off]>);
-
-TRAD_SYNOPSIS
- #include <unistd.h>
- ssize_t pwrite(<[fd]>, <[buf]>, <[n]>, <[off]>)
- int <[fd]>;
- const void *<[buf]>;
- size_t <[n]>;
- off_t <[off]>;
-
- ssize_t _pwrite_r(<[rptr]>, <[fd]>, <[buf]>, <[n]>, <[off]>)
- struct _reent *<[rptr]>;
- int <[fd]>;
- const void *<[buf]>;
- size_t <[n]>;
- off_t <[off]>;

-DESCRIPTION
-The <<pwrite>> function is similar to <<write>>. One difference is that
-<<pwrite>> has an additional parameter <[off]> which is the offset to
-position in the file before writing. The function also differs in that
-the file position is unchanged by the function (i.e. the file position
-is the same before and after a call to <<pwrite>>).
-
-The <<_pwrite_r>> function is the same as <<pwrite>>, only a reentrant
-struct pointer <[rptr]> is provided to preserve reentrancy.
-
-RETURNS
-<<pwrite>> returns the number of bytes written or <<-1>> if failure occurred.
-
-PORTABILITY
-<<pwrite>> is non-ANSI and is specified by the Single Unix Specification.
-
-Supporting OS subroutine required: <<write>>, <<lseek>>.
