form_field_info(3X)

✨ NAME ✨

okay so bestie, welcome to form_field_info(3X) from the Library calls section — this one is literally about retrieving field characteristics. 💅

• dynamic_field_info, field_info — retrieve field characteristics

🦋 SYNOPSIS 🦋

       #include <form.h>

       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);

---

💖 DESCRIPTION 💖

The function field_info returns the sizes and other attributes passed in to the field at its creation time. It’s giving “receipts from when this field was born” energy. 🧾✨

The attributes are:

• height
• width
• row of upper-left corner
• column of upper-left corner
• number off-screen rows
• 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. No cap, it just gets zeroed out. 🫶

A field can be made dynamic by turning off the O_STATIC option with field_opts_off. That’s the lowkey switch-up that unlocks dynamic behavior. 🔥

---

🌸 RETURN VALUE 🌸

These routines return one of the following:

• E_OK — the routine succeeded. slay.
• E_SYSTEM_ERROR — System error occurred (see errno(3)). 😭
• E_BAD_ARGUMENT — Routine detected an incorrect or out-of-range argument. not the vibe. 💀

---

🎀 PORTABILITY 🎀

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. history lesson, but make it niche. 📚

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. so yeah, check your implementation’s vibe first. 👀
