NAME

       genders_isnode, genders_isattr, genders_isattrval - node, attribute, value check routines

SYNOPSIS

       #include <genders.h>

       int genders_isnode(genders_t handle, const char *node);

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

       int genders_isattrval(genders_t handle, const char *attr, const char *val);

DESCRIPTION

       genders_isnode()  tests  if  the node pointed to by node is listed in the genders file.  If node is NULL,
       the current node is tested.

       genders_isattr() tests if the attribute pointed to by attr is listed for some node in the genders file.

       genders_isattrval() tests if the attribute pointed to by attr is equal to the value pointed to by val for
       some node in the genders file.

RETURN VALUES

       For  genders_isnode(),  if  node is listed in the genders file, 1 is returned.  If it is not listed, 0 is
       returned.

       For genders_isattr(), if attr is listed in the genders file, 1 is returned.  If it is not  listed,  0  is
       returned.

       For  genders_isattrval(), if attr=val is listed in the genders file, 1 is returned.  If it is not listed,
       0 is returned.

       On error, all three return -1 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.
