sd_bus_message_append_strv − Attach an array of strings to a message
#include <elogind/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.
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.
These APIs are implemented as a shared library, which can be compiled and linked to with the libelogind pkg-config(1) file.
