QB_IPCC_RECV(3)

💖 QB_IPCC_RECV(3) 💖

okay so bestie, we're in the libqb Programmer's Manual today and this little cutie is qb_ipcc_recv — she receives a response, and honestly? she's carrying the whole client-side conversation. pull up a chair. 🫶

✨ NAME ✨

qb_ipcc_recv — receive a response. that's it, that's the gig. 💅

---

🌸 SYNOPSIS 🌸

#include <qb/qbipcc.h>

ssize_t qb_ipcc_recv(
    qb_ipcc_connection_t   *c,           /* connection instance */
    void                   *msg_ptr,     /* pointer to a message buffer to receive into */
    size_t                  msg_len,     /* the size of the buffer */
    int32_t                 ms_timeout   /* max time to wait for a response */
);

four args, one return value, zero drama. we love a clean signature. ✨

🎀 PARAMS 🎀

• c — your connection instance. the whole relationship, basically. 👑
• msg_ptr — a pointer to a message buffer that she's gonna receive into. bring your own buffer, she's not lending you one.
• msg_len — the size of that buffer. and listen, she needs the actual size, not the vibe of the size. 🙈
• ms_timeout — max time to wait for a response, in milliseconds. so she'll hang out, but only for that long. she's patient, not a doormat. 💅

🦋 DESCRIPTION 🦋

okay so this section is literally empty in the source. no notes. nothing. the description is giving silence, and honestly? the NOTE below is doing all the heavy lifting. scroll down, bestie. 😭

---

🌈 RETURN VALUE 🌈

(size recv'ed, -errno == error)

so: on the good path you get back the size you received. on the bad path you get a negative errno. that's the whole mood ring. green flag or red flag, no in between. 🔥

---

💜 NOTE 💜

that msg_ptr will include a qb_ipc_response_header at the top of the message.

fr fr, do not skip this one. the header is at the top of your message, so if you start reading from byte zero expecting pure payload, you're gonna have a bad time. the response header rides first. periodt. 🎀
