ICONV_OPEN_INTO(3)

okay so bestie, you found iconv_open_into(3) from the Library Functions Manual, and we're gonna get you comfy with it 💅✨

🌸 NAME 🌸

iconv_open_into — initialize descriptor for character set conversion

✨ SYNOPSIS ✨

#include <iconv.h>

int iconv_open_into (const char* tocode, const char* fromcode,
                     iconv_allocation_t* resultp);

💖 DESCRIPTION 💖

okay so iconv_open_into is the setup bestie: it initializes a conversion descriptor that's suitable for converting byte sequences from character encoding fromcode to character encoding tocode. The conversion descriptor gets stored in the memory pointed to by resultp — yes, it's giving "you bring the storage, I bring the descriptor" energy 🫶

The values permitted for fromcode and tocode are the same as for the function iconv_open. same guest list, different party 🎀

After a successful return from this function, resultp can be used as an iconv_t object with the iconv function. literally main character energy: your little resultp storage gets to show up as an iconv_t and work with iconv 🔥

🎀 RETURN VALUE 🎀

The iconv_open_into function fills *resultp and returns 0 if it succeeds. In case of error, it sets errno and returns -1. no cap: success is 0, failure is -1 plus errno, periodt 💀

💀 ERRORS 💀

The following error can occur, among others:

• EINVAL — the conversion from fromcode to tocode is not supported by the implementation. not every encoding pairing gets an invite, and that's on the implementation 🙈

🧚 CONFORMING TO 🧚

This function is implemented only in GNU libiconv and not in other iconv implementations. It is not backed by a standard. You can test for its presence through (_LIBICONV_VERSION >= 0x010D). iykyk — GNU libiconv only, no standard backing it, and that version check is your vibe check ⭐
