mariadb_dyncol_list_num(3)

💖 mariadb_dyncol_list_num 💖

okay so bestie, welcome to the MariaDB Connector/C corner of the man pages, and today's main character is mariadb_dyncol_list_num — yes she's giving dynamic column energy and yes she is literally about to hand you a whole list of numbers. no cap. 🎀

✨ Name ✨

mariadb_dyncol_list_num — lists numeric column keys in a dynamic column 🦋

✨ Synopsis ✨

#include <mariadb_dyncol.h>

enum enum_dyncol_func_result
mariadb_dyncol_list_named(DYNAMIC_COLUMN *str,
                          uint *column_count,
                          uint **column_numbers);

✨ Description ✨

she lists the column numbers inside a dynamic column. that's it, that's the vibe. 💅

✨ Parameter ✨

• *str — the dynamic column. the actual thing we're snooping through 🌸
• *column_count — a pointer to an unsigned integer, and that integer is where the number of columns lives 🫶
• **column_numbers — a pointer to an array of column numbers, and that array is where the numbers themselves live. double pointer behavior, she's iconic like that ⭐

✨ Return value ✨

returns ER_DYNCOL_OK when it goes well, otherwise it's an error. periodt. 😭

✨ Notes ✨

• the application program needs to free the allocated memory for the column_count and column_numbers parameters. do not forget this one bestie — that memory is yours to release, not hers 🙈
