sd_bus_message_append_strv(3) 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

The sd_bus_append_append_strv() function described here is available as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
