GETGROUPLIST(3) FreeBSD Library Functions Manual GETGROUPLIST(3) NAME getgrouplist -- calculate group access list LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <unistd.h> int getgrouplist(const char *name, gid_t basegid, gid_t *groups, int *ngroups); DESCRIPTION The getgrouplist() function reads through the group file and calculates the group access list for the user specified in name. The basegid is au- tomatically included in the groups list. Typically this value is given as the group number from the password file. 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 and -1 if the size of the group list is too small to hold all the user's groups. Here, 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) HISTORY The getgrouplist() function first appeared in 4.4BSD. FreeBSD 13.0 October 26, 2014 FreeBSD 13.0
