PUTGRENT(3) Linux Programmer's Manual PUTGRENT(3)
putgrent - write a group database entry to a file
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <grp.h> int putgrent(const struct group *restrict grp, FILE *restrict stream);
The putgrent() function is the counterpart for fgetgrent(3). The function writes the content of the provided struct group into the stream. The list of group members must be NULL-terminated or NULL-initialized. The struct group is defined as follows: struct group { char *gr_name; /* group name */ char *gr_passwd; /* group password */ gid_t gr_gid; /* group ID */ char **gr_mem; /* group members */ };
The function returns zero on success, and a nonzero value on error.
