The "read pointer" in the message must be right before an array of + strings (D-Bus type as), object paths (D-Bus type ao), or + signatures (D-Bus type ag). On success, a pointer to a + NULL-terminated array of strings (strv) is returned in the output parameter + l. Note that ownership of this array is transferred to the caller. Hence, the + caller is responsible for freeing this array and its contents. + + sd_bus_message_read_strv_extend() is similar, but the second parameter is an + input-output parameter. If *l is NULL, if behaves identically + to sd_bus_message_read_strv(). Otherwise, *l must point to a + strv, which will be reallocated and extended with additional strings. This function is particularly + useful when combining multiple lists of strings in a message or messages into a single array of strings. + + + + + Return Value + + On success, these functions return a non-negative integer.
