✨ PX_GET_DATA_BYTE ✨

okay so bestie, welcome to PX_get_data_byte from the Library Functions Manual 💖 — she's a lil legend in the paradox library and she's here to help you get one (1) single byte out of a data field. let's get into it 🦋

💅 NAME 💅

PX_get_data_byte — Get value from byte data field ✨

🌸 SYNOPSIS 🌸

#include <paradox.h>

int PX_get_data_byte(pxdoc_t *pxdoc, char *data, int len, char *value)

🎀 DESCRIPTION 🎀

okay so what she does is: she takes a data field that's made up of a single byte and converts it into a byte for the host architecture. and like, pls pls pls — you should use this function instead of accessing the data directly. no cap. she's the whole vibe, don't go poking at the raw bytes yourself 🙈

data points to the start of the data field in the record. and the way you figure out where that is? you sum up all the field lengths before the field you wanna operate on, and add that to the base pointer of the record. that's the math, that's the assignment, you got this 🫶

Note: this function is deprecated and obsolete if PX_retrieve_record(3) is used. like, it's giving legacy. if you're already using PX_retrieve_record(3) you literally do not need her 💀

⭐ RETURN VALUE ⭐

  • returns 0 if the value is NULL
  • returns -1 in case of an error 😭
  • returns 1 otherwise 👑
