NAME¶
sd_bus_message_read_strv - Access an array of strings in a messageSYNOPSIS¶
#include <systemd/sd-bus.h>
int sd_bus_message_read_strv(sd_bus_message *m, char ***l);
DESCRIPTION¶
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.RETURN VALUE¶
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.
