GENDERS_ISNODE(3)

💖 GENDERS_ISNODE — bestie's guide to node/attr/value check routines 💖

ok so this is GENDERS_ISNODE(3) from the LIBGENDERS crew, and it's literally three lil check-in routines that answer the question "hey, is this a thing in the genders file?" 🎀

They live in section 3 of the manual, they're part of libgenders, and they're your new besties. Let's go 💅

---

✨ NAME ✨

genders_isnode, genders_isattr, genders_isattrval — node, attribute, value check routines

Like, the trio. The girlies. The vibe check squad. 🫶

---

🌸 SYNOPSIS 🌸

#include <genders.h>

int genders_isnode(genders_t handle, const char *node);

int genders_isattr(genders_t handle, const char *attr);

int genders_isattrval(genders_t handle, const char *attr, const char
*val);

ok first of all? #include <genders.h>. Always. Non-negotiable. Periodt. ✨

---

🦋 DESCRIPTION 🦋

genders_isnode() — this one tests if the node pointed to by node is listed in the genders file. and if node is NULL? bestie, it just tests the current node instead. main character energy honestly 😌

genders_isattr() — tests if the attribute pointed to by attr is listed for some node in the genders file. not a specific one, just... somewhere. it's giving "do you know her" 👑

genders_isattrval() — tests if the attribute pointed to by attr is equal to the value pointed to by val for some node in the genders file. so like, the full package. the pair. the duo. 💖

🌈 RETURN VALUES 🌈

For genders_isnode():

• if node is listed in the genders file → 1 is returned 🔥
• if it is not listed → 0 is returned 💀

For genders_isattr():

• if attr is listed in the genders file → 1 is returned 🔥
• if it is not listed → 0 is returned 💀

For genders_isattrval():

• if attr=val is listed in the genders file → 1 is returned 🔥
• if it is not listed → 0 is returned 💀

and on error? ALL THREE of them return -1, no cap. and an error code gets returned in handle. you can grab that error code with genders_errnum(3), and a lil description of it with genders_strerror(3). the error codes are defined in genders.h. 💅

---

💜 ERRORS 💜

• GENDERS_ERR_NULLHANDLE — the handle parameter is NULL. bestie the handle has to be created with genders_handle_create(3) first, we can't work with nothing 🙈
• GENDERS_ERR_NOTLOADED — genders_load_data(3) has not been called to load genders data. no data loaded, no answers, sorry babe 😭
• GENDERS_ERR_PARAMETERS — an incorrect parameter has been passed in. wrong girl, wrong vibe, try again 💀
• GENDERS_ERR_MAGIC — handle has an incorrect magic number. this means handle does not point to a genders handle, OR it's been destroyed by genders_handle_destroy(3). she's gone, she's not coming back 🧚
