int field_info(const FIELD *field, int *rows, int *cols,
int *frow, int *fcol, int *nrow, int *nbuf);
int dynamic_field_info(const FIELD *field, int *rows, int *cols, *max);
The function field_info returns the sizes and other attributes passed
in to the field at its creation time. The attributes are: height,
width, row of upper-left corner, column of upper-left corner, number
off-screen rows, and number of working buffers.
The function dynamic_field_info returns the actual size of the field,
and its maximum possible size. If the field has no size limit, the
location addressed by the third argument will be set to 0. (A field
can be made dynamic by turning off the O_STATIC).
These routines return one of the following:
E_OK The routine succeeded.
System error occurred (see errno).
Routine detected an incorrect or out-of-range argument.
