NAMEsd_bus_message_verify_type − Check if the message has specified type at the current location

---

SYNOPSIS#include <systemd/sd−bus​.h>int sd_bus_message_verify_type(sd_bus_message *m, char type, const char* contents);

---

DESCRIPTIONsd_bus_message_verify_type() checks if the complete type at the current location in the message m matches the specified type and contents​. If non−zero, parameter type must be one of the types specified in sd_bus_message_append(1)​. If non−null, parameter contents must be a valid sequence of complete types​. If both type and contents are specified type must be a container type​. If type is specified, the type in the message must match​. If contents is specified, the type in the message must be a container type with this signature​.

---

RETURN VALUEOn success, this call returns true if the type matches and zero if not (the message m contains different data or the end of the message has been reached)​. On failure, it returns a negative errno−style error code​.

---

ErrorsReturned errors may indicate the following problems: −EINVAL m or both type and contents are NULL​. Arguments do not satisfy other constraints listed above​. −EPERM Message m is not sealed​.

---

NOTESThese APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd ​pkg-config(1) file​.
