-.TH OUROBOROS_INIT 3 2017-04-10 GNU "Ouroboros Programmer's Manual"
-
-.SH NAME
-
-ouroboros_init, ouroboros_fini \- initialize and finalize an
-application for using Ouroboros
-
-.SH SYNOPSIS
-
-.B #include <ouroboros/dev.h>
-
-\fBint ouroboros_init(char * \fIapn\fB);\fR
-
-\fBvoid ouroboros_fini(void);\fR
-
-Compile and link with \fI-louroboros\fR.
-
-.SH DESCRIPTION
-
-The \fBouroboros_init\fR() call initializes an application process
-instance for using the Ouroboros IPC infrastructure. If the
-application is a server or peer, a \fBchar * \fIapn\fR has to be
-provided indicating the application process that this instance belongs
-to. This is usually argv[0]. A client application may pass NULL. The
-\fBouroboros_fini\fR() call will release all resources allocated by
-\fBouroboros_fini\fR().
-
-\fBouroboros_init\fR() and \fBouroboros_fini\fR() should be called
-only once in the application.
-
-.SH RETURN VALUE
-
-On success, \fBouroboros_init\fR() returns 0. On failure, a negative
-value indicating the error will be returned. The
-\fBouroboros_fini\fR() function has no return value.
-
-.SH ERRORS
-
-\fBouroboros_init\fR() can return the following errors:
-
-.B -EIRMD
-Failed to contact an IRMd instance.
-
-.B -ENOMEM
-Insufficient system resources to intialize the application.
-
-.SH ATTRIBUTES
-
-For an explanation of the terms used in this section, see
-\fBattributes\fR(7).
