   selinux_file_context_cmp    ( 3 )

---

---

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.
