security_class_to_string(3)SELinux API documentatiosecurity_class_to_string(3)
NAME
security_class_to_string, security_av_perm_to_string, string_to_secu-
rity_class, string_to_av_perm, security_av_string, mode_to_secu-
rity_class - convert between SELinux class and permission values and
string names. print_access_vector - display an access vector in human-
readable form.
SYNOPSIS
#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, ac-
cess_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);
DESCRIPTION
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 vec-
tor 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 representa-
tion 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.
RETURN VALUE
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.
ERRORS
EINVAL A class or access vector argument is not recognized by the cur-
rently loaded policy.
ENOMEM An attempt to allocate memory failed.
