NAME

       genders_getattr - get attributes from a genders file

SYNOPSIS

       #include <genders.h>

       int  genders_getattr(genders_t  handle,  char  *attrs[], char *vals[], int len, const char
       *node);

DESCRIPTION

       genders_getattr() gets the attributes and values for the node pointed to by node.  If node
       is  NULL,  attributes  and  values are retrieved for the current node.  The attributes are
       stored in the attribute list pointed to by attrs and the attribute values  are  stored  in
       vals.   If attribute values are not desired, vals can be set to NULL.  len should indicate
       the number of elements that can be stored in both the attribute list and attribute  values
       list.

       To  avoid  passing  in  a  list  that  is not large enough to store all the attributes and
       attribute values, genders_getmaxattrs(3) should be used to determine the minimum number of
       elements  attrs  and  vals  should  be  able  to  store.   genders_attrlist_create(3)  and
       genders_vallist_create(3) could be used to create lists that are guaranteed  to  be  large
       enough to store all attributes and attribute values.

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.

ERRORS

       GENDERS_ERR_NULLHANDLE
              The  handle  parameter  is  NULL.   The  genders  handle  must  be   created   with
              genders_handle_create(3).

       GENDERS_ERR_NOTLOADED
              genders_load_data(3) has not been called to load genders data.

       GENDERS_ERR_OVERFLOW
              The  list  pointed  to  by  attrs  or  vals  is  not  large enough to store all the
              attributes or attribute values.

       GENDERS_ERR_PARAMETERS
              An incorrect parameter has been passed in.

       GENDERS_ERR_NULLPTR
              A null pointer has been found in the list passed in.

       GENDERS_ERR_NOTFOUND
              The node pointed to by node cannot be found in the genders file  or  if  node=NULL,
              the machine genders is running on is not listed in the genders database.

       GENDERS_ERR_MAGIC
              handle has an incorrect magic number.  handle does not point to a genders handle or
              handle has been destroyed by genders_handle_destroy(3).
