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, int *max);
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 option with field_opts_off.
5 E_OK The routine succeeded.
5 E_SYSTEM_ERROR System error occurred (see errno).
5 E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.
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.
