The <pwd.h> header shall define the structpasswd, structure, which shall include at least the following members: char *pw_name User's login name. uid_t pw_uid Numerical user ID. gid_t pw_gid Numerical group ID. char *pw_dir Initial working directory. char *pw_shell Program to use as shell. The <pwd.h> header shall define the gid_t, uid_t, and size_t types as described in <sys/types.h>. The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided. void endpwent(void); struct passwd *getpwent(void); struct passwd *getpwnam(const char *); int getpwnam_r(const char *, struct passwd *, char *, size_t, struct passwd **); struct passwd *getpwuid(uid_t); int getpwuid_r(uid_t, struct passwd *, char *, size_t, struct passwd **); void setpwent(void); Thefollowingsectionsareinformative.
