SD_BUS_MESSAGE_APPEND_STRV(3) sd_bus_message_append_strv SD_BUS_MESSAGE_APPEND_STRV(3)

NAME

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.
