context_new3
Routines to manipulate selinux security contexts
Usage
#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);
Overview
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.
