blcompare(3TSOL) Trusted Extensions Library Functions blcompare(3TSOL) NAME
blcompare, blequal, bldominates, blstrictdom, blinrange - compare binary labels SYNOPSIS
cc [flag...] file... -ltsol [library...] #include <tsol/label.h> int blequal(const m_label_t *label1, const m_label_t *label2); int bldominates(const m_label_t *label1, const m_label_t *label2); int blstrictdom(const m_label_t *label1, const m_label_t *label2); int blinrange(const m_label_t *label, const brange_t *range); DESCRIPTION
These functions compare binary labels for meeting a particular condition. The blequal() function compares two labels for equality. The bldominates() function compares label label1 for dominance over label label2. The blstrictdom() function compares label label1 for strict dominance over label label2. The blinrange() function compares label label for dominance over range->lower_bound and range->upper_bound for dominance over level label. RETURN VALUES
These functions return non-zero if their respective conditions are met, otherwise zero is returned. ATTRIBUTES

m_label(3TSOL) Trusted Extensions Library Functions m_label(3TSOL) NAME
m_label, m_label_alloc, m_label_dup, m_label_free - m_label functions SYNOPSIS
cc [flag...] file... -ltsol [library...] #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); 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 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. 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. ERRORS
The m_label_alloc() function will fail if: EINVAL Invalid parameter. ENOMEM The physical limits of the system are exceeded by size bytes of memory which cannot be allocated. ATTRIBUTES
