#include <tsol/label.h> 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);
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:
A Mandatory Access Control (MAC) label.
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 caller is responsible for freeing the allocated resources by calling m_label_free().
The m_label_free() function frees resources that are associated with the previously allocated label.
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.
The m_label_alloc() function will fail if:
The physical limits of the system are exceeded by size bytes of memory which cannot be allocated.
