MFS CHGFILEPTR

Move the file's logical read position pointer.

Syntax
int far pascal MFS_CHGFILEPTR(offset, type)

Parameters

 * offset:is the signed offset which depending on the type parameter is used to determine the new position within the file.
 * type:indicates the basis of a seek operation.
 * 0 indicates seek relative to beginning of file.
 * 1 indicates seek relative to current position within the file.
 * 2 indicates seek relative to end of file.

Returns

 * 0: If no error is detected, a zero error code is returned.
 * non-zero:If an error is detected, a non-zero error code is returned.

Remarks
The file system may want to take the seek operation as a hint that an I/O operation is about to take place at the new position and initiate a positioning operation on sequential access media or read-ahead operation on other media.
