get_version_number(9)

🌸 NAME 🌸

okay so this is get_version_number(9), and it's from the Kernel API Manual — very demure, very kernel-coded. what it does is literally: get_version_number — decide the version number from argv. slay.

✨ SYNOPSIS ✨

int get_version_number (int argc , char **argv , char **error_ptr ,
       unsigned int *version_ptr );

🧚 ARGUMENTS 🧚

• argc — the number of table values. bestie, it's the count.
• argv — the array of table values. yes, the whole little lineup.
• error_ptr — a pointer to return a error string in. so if something goes sideways, the error string goes here.
• version_ptr — a pointer to return the version. that's the whole point, iykyk.

🔥 RETURN 🔥

VDO_SUCCESS or an error code. no cap, that's the entire return situation.
