getgrouplist

GETGROUPLIST(3) 					   BSD Library Functions Manual 					   GETGROUPLIST(3)

NAME

     getgrouplist -- calculate partial group access list

LIBRARY

     Standard system libraries.

SYNOPSIS

     #include <unistd.h>

     int
     getgrouplist(const char *name, int basegid, int *groups, int *ngroups);

DESCRIPTION

     The getgrouplist() function obtains information from opendirectoryd(8) to construct the group access list for the user specified in name.
     The basegid is automatically included in the groups list.	Typically this value is given as the default group number from the user's account
     record.

     The resulting group list is returned in the array pointed to by groups.  The caller specifies the size of the groups array in the integer
     pointed to by ngroups; the actual number of groups found is returned in ngroups.

RETURN VALUES

     The getgrouplist() function returns 0 on success.	If the size of the group list is too small to hold all the user's groups, getgrouplist()
     returns -1 to indicate failure.  In this case, the group array will be filled with as many groups as will fit.

FILES

     /etc/group  group membership list

SEE ALSO

     setgroups(2), initgroups(3), opendirectoryd(8).

HISTORY

     The getgrouplist() function first appeared in 4.4BSD.
