Let's use it here too. .../glibc$ grep_glibc_prototype posix_spawn posix/spawn.h:72: extern int posix_spawn (pid_t *__restrict __pid, const char *__restrict __path, const posix_spawn_file_actions_t *__restrict __file_actions, const posix_spawnattr_t *__restrict __attrp, char *const __argv[__restrict_arr], char *const __envp[__restrict_arr]) __nonnull ((2, 5)); .../glibc$ I conciously did an exception with respect to the right margin of the rendered page. Instead of having the right margin at 78 as usual (per Branden's recommendation), I let it use col 79 this time, to avoid breaking the prototype in an ugly way, or shifting all of the parameters to the left, unaligned with respect to the function parentheses.
