NAME

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.

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 , 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 );

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.

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 currently loaded policy.

ENOMEM

An attempt to allocate memory failed.
