SD_BUS_MESSAGE_READ_STRV(3)bus_message_read_strvBUS_MESSAGE_READ_STRV(3)
sd_bus_message_read_strv - Access an array of strings in a
message
#include <systemd/sd-bus.h>
int sd_bus_message_read_strv(sd_bus_message *m, char ***l);
sd_bus_message_read_strv() gives access to an array of strings in
message m. The "read pointer" in the message must be right before
an array of strings. On success, a pointer to the NULL-terminated
array of strings 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.
On success, sd_bus_message_read_strv() returns a non-negative
integer. On failure, it returns a negative errno-style error
code.
Errors
Returned errors may indicate the following problems:
-EINVAL
m or l are NULL.
-EPERM
The message is not sealed.
-EBADMSG
The message cannot be parsed.
