            Bug ID: 27529
           Summary: posix_spawn(3) should be using restrict
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: alx.manpages at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

POSIX.1 uses 'restrict':

[
SYNOPSIS
       #include <spawn.h>

       int posix_spawnp(pid_t *restrict pid, const char *restrict file,
           const posix_spawn_file_actions_t *file_actions,
           const posix_spawnattr_t *restrict attrp,
           char *const argv[restrict], char *const envp[restrict]);

] [man 3p posix_spawnp]

Curiously, the almost identical posix_spawn(3) is using 'restrict' in glibc:

=============================  posix_spawn
posix/spawn.h:72:
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));
=============================  posix_spawnp
posix/spawn.h:85:
int posix_spawnp (pid_t *pid, const char *file,
                         const posix_spawn_file_actions_t *file_actions,
                         const posix_spawnattr_t *attrp,
                         char *const argv[], char *const envp[])
    nonnull ((2, 5));

Is this about posix_spawn or posix_spawnp?

Ahhh, yes.  It was a typo.

This is about posix_spawnp().
