getpwnam.3: SYNOPSIS: Use 'restrict' in prototypes
POSIX does NOT specify these functions to use 'restrict'.
However, glibc uses 'restrict' in getpwnam_r(), getpwuid_r().
Let's use it here too.
.../glibc$ grep_glibc_prototype getpwnam_r
pwd/pwd.h:151:
extern int getpwnam_r (const char *__restrict __name,
struct passwd *__restrict __resultbuf,
char *__restrict __buffer, size_t __buflen,
struct passwd **__restrict __result)
__nonnull ((1, 2, 3, 5));
.../glibc$ grep_glibc_prototype getpwuid_r
pwd/pwd.h:145:
extern int getpwuid_r (__uid_t __uid,
struct passwd *__restrict __resultbuf,
char *__restrict __buffer, size_t __buflen,
struct passwd **__restrict __result)
__nonnull ((2, 3, 5));
