initgroups(3c)

Standard C Library Functions                                    initgroups(3C)



NAME
       initgroups - initialize the supplementary group access list

SYNOPSIS
       #include <grp.h>
       #include <sys/types.h>

       int initgroups(const char *name, gid_t basegid);

DESCRIPTION
       The  initgroups()  function  reads  the group database to get the group
       membership for the user specified by name, and initializes the  supple‐
       mentary  group access list of the calling process (see getgrnam(3C) and
       getgroups(2)). The basegid group ID is also included in the  supplemen‐
       tary  group  access  list. This is typically the real group ID from the
       user database.


       While scanning the group database, if the number of  groups,  including
       the  basegid  entry,  exceeds NGROUPS_MAX, subsequent group entries are
       ignored.

RETURN VALUES
       Upon successful completion, 0 is returned. Otherwise,  −1  is  returned
       and errno is set to indicate the error.

ERRORS
       The  initgroups()  function  will fail and not change the supplementary
       group access list if:

       EPERM    The {PRIV_PROC_SETID} privilege is not asserted in the  effec‐
                tive set of the calling process.
