getpwnam, getpwuid − get password file entry
#include
<pwd.h>
#include <sys/types.h>
struct passwd *getpwnam(const char * name);
struct passwd *getpwuid(uid_t uid);
The getpwnam() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that matches the user name name.
The getpwuid() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that matches the user uid uid.
The passwd structure is defined in <pwd.h> as follows:
struct passwd {
/* user name */ | |||
/* user password */ | |||
/* user id */ | |||
/* group id */ |
char *pw_gecos; /* real name */
/* home directory */ |
char *pw_shell; /* shell
program */
};
The getpwnam() and getpwuid() functions return the passwd structure, or NULL if the matching entry is not found or an error occurs.
