calculate partial group access list
Standard system libraries.
#include

int
getgrouplist
(const
char *name, int
basegid, int
*groups, int
*ngroups);
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.
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.
The getgrouplist
() function first appeared
in 4.4BSD.
