sd_bus_message_append_strv — Attach an array of strings to a message
Synopsis
#include <systemd/sd-bus.h>
int sd_bus_message_append_strv(sd_bus_message *m, char **l);
Description
The sd_bus_message_append function can be used to append an array of strings to message m. The parameter l shall point to a NULL-terminated array of pointers to NUL-terminated strings. Each string must satisfy the same constraints as described for the "s" type in sd_bus_message_append_basic(3).
The memory pointed at by p and the contents of the strings themselves are copied into the memory area containing the message and may be changed after this call. Note that the signature of l parameter is to be treated as const char *const *, and the contents will not be modified.
Return Value
On success, this call returns 0 or a positive integer. On failure, a negative errno-style error code is returned.
Errors
Returned errors may indicate the following problems:
- -EINVAL
Specified parameter is invalid.
- -EPERM
Message has been sealed.
- -ESTALE
Message is in invalid state.
- -ENXIO
Message cannot be appended to.
- -ENOMEM
Memory allocation failed.
Notes
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
