NAME        top

       sd_bus_message_append_strv - Attach an array of strings to a       message

SYNOPSIS        top

#include <systemd/sd-bus.h>int sd_bus_message_append_strv(sd_bus_message *m, char **l);

DESCRIPTION        top

       Thesd_bus_message_append()function can be used to append an       array of strings to messagem. The parameterl shall point to aNULL-terminated array of pointers toNUL-terminated strings. Each       string must satisfy the same constraints as described for the "s"       type insd_bus_message_append_basic(3).       The memory pointed at byp 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 ofl       parameter is to be treated asconst char *const *, and the       contents will not be modified.

RETURN VALUE        top

       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        top

       Functions described here are available as a shared library, which       can be compiled against and linked to with thelibsystemd pkg-config(1) file.       The code described here usesgetenv(3), which is declared to be       not multi-thread-safe. This means that the code calling the       functions described here must not callsetenv(3) from a parallel       thread. It is recommended to only do calls tosetenv()from an       early phase of the program when no other threads have been       started.
