getgid(2) [freebsd man page]

GETGID(2)						      BSD System Calls Manual							 GETGID(2)

NAME
getgid, getegid -- get group process identification LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <unistd.h> gid_t getgid(void); gid_t getegid(void); DESCRIPTION
The getgid() system call returns the real group ID of the calling process, getegid() returns the effective group ID of the calling process. The real group ID is specified at login time. The real group ID is the group of the user who invoked the program. As the effective group ID gives the process additional permissions dur- ing the execution of ``set-group-ID'' mode processes, getgid() is used to determine the real-user-id of the calling process. ERRORS
The getgid() and getegid() system calls are always successful, and no return value is reserved to indicate an error. SEE ALSO
getuid(2), issetugid(2), setgid(2), setregid(2) STANDARDS
The getgid() and getegid() system calls are expected to conform to ISO/IEC 9945-1:1990 (``POSIX.1''). BSD
