man genders_getattr_all (Fonctions bibliothèques) - get all the attributes stored in a genders file
NAME
genders_getattr_all - get all the attributes stored in a genders file
SYNOPSIS
#include <genders.h>
int genders_getattr_all(genders_t handle, char *attrs[], int len);
DESCRIPTION
genders_getattr_all() gets all the attributes found in the genders file associated with handle. The attributes are stored in the attribute list pointed to by attrs. len should indicate the number of elements that can be stored in the attribute list.
To avoid passing in a list that is not large enough to store all the
attributes,
genders_getnumattrs(3)
should be used to determine the minimum number of elements attrs
should be able to store.
genders_attrlist_create(3)
could be used to create a list that is guaranteed to be large enough
to store all attributes.
RETURN VALUES
On success, the number of attributes stored in attrs is
returned. On error, -1 is returned, and an error code is returned in
handle. The error code can be retrieved via
genders_errnum(3)
, and a description of the error code can be retrieved via
genders_strerror(3).
Error codes are defined in genders.h.
