ustrerror(3alleg4)

✨ NAME ✨

ustrerror — returns a string describing errno, bestie. This one lives in the Allegro manual, page ustrerror(3alleg4), and it’s part of the Allegro game programming library. 💖

🌸 SYNOPSIS 🌸

#include <allegro.h>

const char *ustrerror(int err);

🦋 DESCRIPTION 🦋

Okay so this function returns a string that describes the error code err, which normally comes from the variable errno. It’s giving “translate the mysterious error number into actual words” energy. ✨

Example:

PACKFILE *input_file = pack_fopen("badname", "r");
if (input_file == NULL)
   allegro_message("%s\nSorry!\n", ustrerror(errno));

👑 RETURN VALUE 👑

Returns a pointer to a static string that should not be modified or freed. If you make subsequent calls to ustrerror(), the string will be overwritten. So don’t clutch that pointer like it’s your emotional support text, because it will absolutely get replaced. 😭💅
