NAME

context_new, context_str, context_free, context_type_get, context_type_set, context_range_get, context_range_set,context_role_get, context_role_set, context_user_get, context_user_set - Routines to manipulate SELinux security contexts

SYNOPSIS

#include <selinux/context.h>

context_t context_new(const char * context_str );

const char * context_str(context_t con );

void context_free(context_t con );

const char * context_type_get(context_t con );

const char * context_range_get(context_t con );

const char * context_role_get(context_t con );

const char * context_user_get(context_t con );

int context_type_set(context_t con , const char * type );

int context_range_set(context_t con , const char * range );

int context_role_set(context_t con , const char * role );

int context_user_set(context_t con , const char * user );

DESCRIPTION

These functions allow an application to manipulate the fields of a security context string without requiring it to know the format of the string.

context_new () returns a new context initialized to a context string.

context_str () returns a pointer to the string value of the context_t , valid until the next call to context_str () or context_free () for the same context_t* .

context_free () frees the storage used by a context.

context_type_get (), context_range_get (), context_role_get (), context_user_get () get a pointer to the string value of a context component.

Note: Values returned by the get functions are only valid until the next call to a set function or context_free () for the same context_t structure.

context_type_set (), context_range_set (), context_role_set (), context_user_set () set a context component.

RETURN VALUE

On failure context_*_set () functions return non-zero and 0 on success.

The other functions return NULL on failure and non-NULL on success.

On failure errno is set appropriately.
