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.
