What does the code do that hacker typer produces?

so I was going on hackertyper and realized how much this looks like HTML code. Am I correct about that? what does the code do? btw here's a snippet`struct group_info init_groups = { .usage = ATOMIC_INIT(2) };

struct group_info *groups_alloc(int gidsetsize){

struct group_info *group_info;

int nblocks;

int i;



nblocks = (gidsetsize + NGROUPS_PER_BLOCK - 1) / NGROUPS_PER_BLOCK;

/* Make sure we always allocate at least one indirect block pointer */
