Имя (Name)

selinux_file_context_cmp - Compare two SELinux security contexts excluding the 'user' component

Синопсис (Synopsis)

#include <selinux/selinux.h>

int selinux_file_context_cmp(const char *a, const char *b);

Описание (Description)

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.

Возвращаемое значение (Return value)

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

Ошибки (Error)

None.

Примечание (Note)

The contexts being compared do not specifically need to be file contexts.

Примеры (Examples)

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.
