selinux_file_context_cmp(3)ibrary Functions Manualelinux_file_context_cmp(3)
selinux_file_context_cmp - Compare two SELinux security contexts
excluding the 'user' component
#include <selinux/selinux.h>
int selinux_file_context_cmp(const char *a,
const char *b);
selinux_file_context_cmp() compares two context strings excluding the
user component with strcmp(3) as shown in the EXAMPLE section.
This is useful as for most object contexts, the user component is not
relevant.
The return values follow the strcmp(3) function, where:
0 if they are equal.
1 if a is greater than b
-1 if a is less than b
None.
The contexts being compared do not specifically need to be file
contexts.
If context a is:
user_u:user_r:user_t:s0
and context b is:
root:user_r:user_t:s0
then the actual strings compared are:
:user_r:user_t:s0 and :user_r:user_t:s0
Therefore they will match and selinux_file_context_cmp() will return
zero.
