GENDERS_GETNODENAME(3)						    LIBGENDERS						    GENDERS_GETNODENAME(3)

NAME
genders_getnodename - get the current node name SYNOPSIS
#include <genders.h> int genders_getnodename(genders_t handle, char *node, int len); DESCRIPTION
genders_getnodename() retrieves the name of the node that the function is being called from. The node name returned is the shortened host- name of the node and is stored in the buffer pointed to be node. len should indicate the length of the buffer. The node returned by gen- ders_getnodename() is the shortened hostname of the node. To avoid passing in a buffer that is not large enough to store the node name, genders_getmaxnodelen(3) should be used to determine the min- imum buffer size that should be used. 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 gen- ders_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 buffer pointed to by node is not large enough to store the node name. GENDERS_ERR_PARAMETERS An incorrect parameter has been passed in. GENDERS_ERR_MAGIC handle has an incorrect magic number. handle does not point to a genders handle or handle has been destroyed by genders_han- dle_destroy(3). FILES

GENDERS_TESTATTR(3)						    LIBGENDERS						       GENDERS_TESTATTR(3)

NAME
genders_testattr - test if a node has an attribute SYNOPSIS
#include <genders.h> int genders_testattr(genders_t handle, const char *node, const char *attr, char *val, int len); int genders_testattrval(genders_t handle, const char *node, const char *attr, const char *val); DESCRIPTION
genders_testattr() tests if the node pointed to by node contains the attribute pointed to by attr. If node is NULL, the current node is tested. If the attribute is found, its value is stored in the buffer pointed to by val. len should indicate the length of the buffer. If the attribute value is not needed, val can be set to NULL. To avoid passing in an attribute value buffer that is not large enough to store the attribute value, genders_getmaxvallen(3) should be used to determine the minimum buffer size that should be used. genders_testattrval() tests if the node pointed to by node contains the attribute pointed to by attr and if that attribute is equal to the attribute value pointed to by val. If val is NULL, only the attribute is tested. RETURN VALUES
For genders_testattr(), if the node contains the attribute, 1 is returned. 0 is returned if the node does not contain the attribute. For genders_testattrval(), if the node contains the attribute and it is equal to the attribute value, 1 is returned. 0 is returned if the node does not contain the attribute, or if the attribute is not equal to the attribute value. For both genders_testattr() and genders_testattrval(), -1 is returned on error, 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 buffer pointed to by val is not large enough to store the attribute value. GENDERS_ERR_PARAMETERS An incorrect parameter has been 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_han- dle_destroy(3). FILES
