Parameters

stream

FILE stream to set the current file position for. [Edit]

pos

The file position to seek to. [Edit]

Returns

Returns 0 if successful; otherwise -1 is returned and Stdlib.GetLastError indicates the error.

Usage

The following errors are specified:

Error	Details
Errno.EBADF	The stream argument is not not a seekable stream
Errno.EINVAL	The whence argument is invalid or the resulting file-position indicator would be set to a negative value.
Errno.EOVERFLOW	The resulting file offset would be a value which cannot be represented correctly in an object of type stem.Int64 for Stdlib.fseek() and Stdlib.ftell().
Errno.ESPIPE	The file descriptor underlying stream is associated with a pipe or FIFO or file-position indicator value is unspecified (see Stdlib.ungetc(3)).

fsetpos may also fail for any of the error specified for the routines Stdlib.fflush(3), Syscall.fstat(2), Syscall.lseek(2), and Stdlib.malloc(3)

[Edit]

Remarks

The fsetpos() function is an alternate interfaces for setting the current position in the file, similar to Stdlib.fseek(), except that the current position is stored in an opaque object of type Mono.Unix.Native.FilePosition pointed to by pos. This provides a portable way to seek to offsets larger than those that can be represented by a long int. It may also store additional state information in the Mono.Unix.Native.FilePosition object to facilitate seeking within files containing multibyte characters with state-dependent encodings. [Edit]
