group_from_gid() -- get group name associated with gid

SYNOPSIS

#include <grp.h>

char *group_from_gid(gid_t gid, int nogroup);

The group_from_gid() function returns the group name associated with the argument gid. The group name is cached so that multiple calls with the same gid do not require additional calls to getgrgid(). If there is no group associated with the gid, a pointer is returned to an ASCII representation of the gid, unless the argument nogroup is non-zero, in which case a NULL pointer is returned.

PARAMETERS

gid: Is the gid for which group name is to be obtained.
nogroup: Indicates what to do if gid is not associated with a group name.

RETURN VALUES

Returns the group name associated with gid or ASCII representation of gid or NULL.

4.4BSD.
