security...o_string(3) SELinux API documentation security...o_string(3)
security_class_to_string, security_av_perm_to_string,
string_to_security_class, string_to_av_perm, security_av_string,
mode_to_security_class - convert between SELinux class and
permission values and string names. print_access_vector -
display an access vector in human-readable form.
#include <selinux/selinux.h>
const char *security_class_to_string(security_class_t tclass);
const char *security_av_perm_to_string(security_class_t tclass,
access_vector_t av);
int security_av_string(security_class_t tclass, access_vector_t
av, char **result);
security_class_t string_to_security_class(const char *name);
security_class_t mode_to_security_class(mode_t mode);
access_vector_t string_to_av_perm(security_class_t tclass, const
char *name);
void print_access_vector(security_class_t tclass, access_vector_t
av);
security_class_to_string() returns a string name for class
tclass, or NULL if the class is invalid. The returned string
must not be modified or freed.
security_av_perm_to_string() returns a string name for the access
vector bit av of class tclass, or NULL if either argument is
invalid. The returned string must not be modified or freed.
security_av_string() computes a full access vector string
representation using tclass and av, which may have multiple bits
set. The string is returned in the memory pointed to by result,
and should be freed by the caller using free(3).
string_to_security_class() returns the class value corresponding
to the string name name, or zero if no such class exists.
mode_to_security_class() returns the class value corresponding to
the specified mode, or zero if no such class exists.
string_to_av_perm() returns the access vector bit corresponding
to the string name name and security class tclass, or zero if no
such value exists.
print_access_vector() displays an access vector in human-readable
form on the standard output stream.
security_av_string() returns zero on success or -1 on error with
errno set appropriately. print_access_vector() does not return a
value. All other functions return zero or NULL on error.
EINVAL A class or access vector argument is not recognized by the
currently loaded policy.
ENOMEM An attempt to allocate memory failed.
