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).
