| The function <STRONG>field_info</STRONG> returns the sizes and other |
| attributes passed in to the field at its creation time. |
| The attributes are: height, width, row of upper-left cor- |
| ner, column of upper-left corner, number off-screen rows, |
| and number of working buffers. |
| |
| The function <STRONG>dynamic_field_info</STRONG> 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 <STRONG>O_STATIC</STRONG> option with <STRONG>field_opts_off</STRONG>. |
| |

| <STRONG>E_SYSTEM_ERROR</STRONG> |
| System error occurred (see <STRONG>errno</STRONG>). |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |

| These routines emulate the System V forms library. They |
| were not supported on Version 7 or BSD versions. |
| |
| A null (zero pointer) is accepted for any of the return |
| values, to ignore that value. Not all implementations |
| allow this, e.g., Solaris 2.7 does not. |
