NAME

t6alloc_blk, t6free_blk- Allocate and free security-attribute control structure and buffer

SYNOPSIS

cc [flags...] file ... -lt6


#include <tsix/t6attrs.h>

t6attr_t t6alloc_blk(t6mask_t mask);
void t6free_blk(t6attr_t t6ctl);

DESCRIPTION

t6alloc_blk() allocates a t6attr_t structure, which is an opaque handle used to access the full set of security attributes supported on the system. See man pages for t6get_attr(3N) and t6set_attr(3N) for more information on how generic TSIX application programs can access security attributes referenced by t6attr_t without knowing how references are built between the t6attr_t structure and the sets of security attributes for each individual TSIX operating system vendor. If t6alloc_blk() is successful, the opaque handle is returned that can be used to set or get individual attributes to or from this control structure. t6alloc_blk() allocates space in the control structure for all attributes specified in the mask parameter.

t6free_blk() should be used in conjunction with t6alloc_blk() to free the opaque control structure and any space within it.

RETURN VALUES

Upon successful completion, t6alloc_blk() returns a pointer to the t6attr_t structure. Upon failure, t6alloc_blk() returns a NULL pointer.

ATTRIBUTES

WARNINGS

For generic TSIX applications, use t6free_blk() to free memory allocated by t6alloc_blk() for better portability.
