#include
m_label_t *m_label_alloc(const m_label_type_t label_type);
int m_label_dup(m_label_t **dst, const m_label_t *src);
void m_label_free(m_label_t *label);
DESCRIPTION
The m_label_alloc() function allocates resources for a new
label. The label_type argument defines the type for a newly
allocated label. The label type can be:MAC_LABEL A Mandatory Access Control (MAC) label.
USER_CLEAR A user clearance.
The m_label_dup() function allocates resources for a new dst
label. The function returns a pointer to the allocated label, which is an exact copy of the src label. The calleris responsible for freeing the allocated resources by cal-
ling m_label_free().
The m_label_free() function frees resources that are associ-
ated with the previously allocated label.RETURN VALUES
Upon successful completion, the m_label_alloc() function
returns a pointer to the newly allocated label. Otherwise,m_label_alloc() returns NULL and errno is set to indicate
the error.Upon successful completion, the m_label_dup() function
returns 0. Otherwise, -1 is returned and errno is set to
indicate the error.SunOS 5.11 Last change: 20 Jul 2007 1
