/***
|
|
*int fgetpos(stream,pos) - Get file position (internal format)
|
|
*
|
|
*Purpose:
|
|
* Fgetpos gets the current file position for the file identified by
|
|
* [stream]. The file position is returned in the object pointed to
|
|
* by [pos] and is in internal format; that is, the user is not supposed
|
|
* to interpret the value but simply use it in the fsetpos call. Our
|
|
* implementation simply uses fseek/ftell.
|
|
*
|
|
*Entry:
|
|
* FILE *stream = pointer to a file stream value
|
|
* fpos_t *pos = pointer to a file position value
|
|
*
|
|
*Exit:
|
|
* Successful fgetpos call returns 0.
|
|
* Unsuccessful fgetpos call returns non-zero (!0) value and sets
|
|
* ERRNO (this is done by ftell and passed back by fgetpos).
|
|
*
|
|
*Exceptions:
|
|
* None.
