sd_bus_message_append_strv - Man Page

#include <systemd/sd-bus​.h>

int sd_bus_message_append_strv(sd_bus_message *m, char **l);

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​.

On success, this call returns 0 or a positive integer​. On failure, a negative errno-style error code is returned​.

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

All functions listed here are thread-agnostic and only a single thread may operate on a given object at any given time​. Different threads may access the same object at different times​. Multiple independent objects may be used from different threads in parallel​.

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​.
