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

Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd pkg-config (1) file.

The code described here uses getenv (3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv (3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.
