INITGROUPS(3) FreeBSD Library Functions Manual INITGROUPS(3) NAME initgroups -- initialize group access list LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <unistd.h> int initgroups(const char *name, gid_t basegid); DESCRIPTION The initgroups() function uses the getgrouplist(3) function to calculate the group access list for the user specified in name. This group list is then setup for the current process using setgroups(2). The basegid is automatically included in the groups list. Typically this value is given as the group number from the password file. RETURN VALUES The initgroups() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error. ERRORS The initgroups() function may fail and set errno for any of the errors specified for the library function setgroups(2). It may also return: [ENOMEM] The initgroups() function was unable to allocate tem- porary storage. SEE ALSO setgroups(2), getgrouplist(3) HISTORY The initgroups() function appeared in 4.2BSD.
