NAME

genders_index_attrvals - internally index attribute values in genders  

SYNOPSIS

#include <genders.h>

int genders_index_attrvals(genders_t handle, const char *attr);


 

DESCRIPTION

genders_index_attrvals() internally indexes attribute values in a genders handle so that genders searches can be done more quickly in the genders_getnodes(3) and genders_isattrval(3) functions.

Only one attribute can be indexed at a time through this function. Subsequent calls to this function with a different attribute will overwrite earlier indexes.
 

RETURN VALUES

On success, 0 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.
