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 - 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>
#include <selinux/flask.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);
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 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.
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.
