       sd_bus_message_read_basic - Read a basic type from a message


       #include <systemd/sd-bus.h>

       int sd_bus_message_read_basic(sd_bus_message *m, char type, void *p);


       sd_bus_message_read_basic() reads a basic type from a message and advances the read
       position in the message. The set of basic types and their ascii codes passed in type are
       described in the D-Bus Specification[1].

       If p is not NULL, it should contain a pointer to an appropriate object. For example, if
       type is 'y', the object passed in p should have type uint8_t *. If type is 's', the object
       passed in p should have type const char **. Note that, if the basic type is a pointer
       (e.g., const char * in the case of a string), the pointer is only borrowed and the
       contents must be copied if they are to be used after the end of the messages lifetime.
       Similarly, during the lifetime of such a pointer, the message must not be modified.

       If there is no object of the specified type at the current position in the message, an
       error is returned.


       On success, sd_bus_message_read_basic() returns 0 or a positive integer. On failure, it
       returns a negative errno-style error code.
