hl_snprintf_resize(9)

okay bestie, welcome to the hl_snprintf_resize(9) page from the Kernel API Manual 💅 this one is all about printing formatted data into a buffer and resizing that buffer when it needs more room, no cap.

💖 NAME 💖

hl_snprintf_resize — print formatted data to buffer, resize as needed ✨

🧚 SYNOPSIS 🧚

int hl_snprintf_resize (char **buf , size_t *size , size_t *offset ,
       const char *format , ... );

🎀 ARGUMENTS 🎀

• buf — buffer double pointer, to be written to and resized, must be either NULL or allocated with vmalloc.
• size — current size of the buffer.
• offset — current offset to write to.
• format — format of the data.
• ... — variable arguments.

✨ DESCRIPTION ✨

so here's the tea: this function writes formatted data into the buffer. if the buffer is not large enough, it will be resized using vmalloc — iconic behavior, honestly. size may be modified if the buffer was resized, and offset will be advanced by the number of bytes written not including the terminating character. iykyk 💫

Returns 0 on success or an error code on failure 🫶

Note, bestie: the buffer has to be manually released using vfree 🎀
