// glob.h — POSIX pathname expansion.
//
// glob(pattern, flags, errfunc, &gb) iterates the directory portion
// of `pattern` via the GS/OS Get_Dir_Entry ($201C) call and stashes
// matches (against `pattern`'s leaf via fnmatch) into gb.gl_pathv.
// On a stub-only build (no real GS/OS dispatcher), glob() returns
// GLOB_NOMATCH with errno=ENOSYS unless GLOB_NOCHECK is set, in
// which case it returns a single-element result containing the
// original pattern.
//
// globfree() releases the malloc'd gl_pathv vector + entries.
