.TH LIBERROR_PRINT_ERROR 3 2019-04-13 liberror
.SH NAME
liberror_print_error \- print an error
.SH SYNOPSIS
.nf
#include <liberror.h>
int liberror_print_error(struct liberror_error *\fIerror\fP, FILE *\fIfp\fP, int \fIreset\fP, const char *\fIprefix\fP);
.fi
.PP
Link with
.IR \-lerror .
.SH DESCRIPTION
The
.BR liberror_print_error ()
function prints the error, including available details, backtrace,
and cause recursively, specified in the
.I error
parameter, or the error currently assigned to the thread if
.I error
is
.IR NULL ,
to
.IR fp ,
or to the standard error if
.I fp
is
.IR NULL .
Unless
.I prefix
is
.I NULL
or the empty string, each printed line will becoming with with
.I prefix
followed by a space and a colon. Under normal usage,
.I prefix
shall be
.I argv[0]
from the
.BR main ()
function.
.PP
If
.I reset
is non-zero,
.I error
will be deallocated with the
.BR liberror_free_error (3)
function, or if
.I error
is
.IR NULL ,
with the
.BR liberror_reset_error (3)
function, which marks that the thread does not have any error
assigned to it. Thus, if
.I error
is
.I NULL
and
.I reset
is non-zero, there is no need to call the
.BR liberror_reset_error (3)
function.
.SH RETURN VALUE
None.
.SH ERRORS
.I errno
will never be changed.
.SH EXAMPLES
None.
.SH APPLICATION USAGE

.SH RATIONALE

.SH FUTURE DIRECTIONS
