-.SH "NAME"
-sd_bus_can_send \- Check which types can be sent over a bus object
-.SH "SYNOPSIS"
-.sp
-.ft B
-.nf
-#include <systemd/sd\-bus\&.h>
-.fi
-.ft
-.HP \w'void\ sd_bus_can_send('u
-.BI "void sd_bus_can_send(sd_bus\ *" "bus" ", char\ " "type" ");"
-.SH "DESCRIPTION"
-.PP
-\fBsd_bus_can_send()\fR
-is mostly used for checking if file descriptor passing is available on the given bus\&.
-\fItype\fR
-can be any of the
-\fBSD_BUS_TYPE\fR
-constants\&.
-.SH "RETURN VALUE"
-.PP
-On failure,
-\fBsd_bus_can_send()\fR
-returns a negative errno\-style error code\&. If values of the given type can be sent over the given bus, it returns a positive integer\&. Otherwise, it returns zero\&.
-.SS "Errors"
-.PP
-Returned errors may indicate the following problems:
-.PP
-\fB\-ENOPKG\fR
-.RS 4
-The bus object
-\fIbus\fR
-could not be resolved\&.
-.RE
-.PP
-\fB\-ENOTCONN\fR
-.RS 4
-The input parameter
-\fIbus\fR
-is
-\fBNULL\fR
-or the bus is not connected\&.
-.RE
-.PP
-\fB\-ECHILD\fR
-.RS 4
-The bus object
-\fIbus\fR
-was created in a different process\&.
-.RE
-.SH "NOTES"
-.PP
-Functions described here are available as a shared library, which can be compiled against and linked to with the
-\fBlibsystemd\fR\ \&\fBpkg-config\fR(1)
-file\&.
-.PP
-The code described here uses
-\fBgetenv\fR(3), which is declared to be not multi\-thread\-safe\&. This means that the code calling the functions described here must not call
-\fBsetenv\fR(3)
-from a parallel thread\&. It is recommended to only do calls to
-\fBsetenv()\fR
-from an early phase of the program when no other threads have been started\&.
