Gets the VI's current field number
#include <ultra64.h> /* os.h */ u32 osViGetCurrentField(void);
Field number (0 or 1)
Returns the field number currently being accessed by the VI. In interlace mode, either an even number (0) or an odd number (1) will be returned as the current field number. In non-interlace mode, an even number (0) will always be returned. In interlace mode, one screen is displayed with two scans, but it is possible with this function to determine whether the first scan or the second scan is currently under way.
osViGetCurrentFramebuffer, osViGetCurrentLine, osViGetCurrentMode, osViGetNextFramebuffer, and osViSwapBuffer
