\&\fIERR_load_strings()\fR registers error strings for library number \fBlib\fR.
|
|
.PP
|
|
\&\fBstr\fR is an array of error string data:
|
|
.PP
|
|
.Vb 5
|
|
\& typedef struct ERR_string_data_st
|
|
\& {

|
\& unsigned long error;
|
|
\& char *string;
|
|
\& } ERR_STRING_DATA;
|
|
.Ve
|
|
.PP
|
|
The error code is generated from the library number and a function and
|
|
reason code: \fBerror\fR = \s-1ERR_PACK\s0(\fBlib\fR, \fBfunc\fR, \fBreason\fR).
|
|
\&\s-1\fIERR_PACK\s0()\fR is a macro.
|
|
.PP
|
|
The last entry in the array is {0,0}.
|
|
.PP
|
|
\&\fIERR_get_next_error_library()\fR can be used to assign library numbers
|
|
to user libraries at run time.
|
|
.SH "RETURN VALUES"

.IX Header "RETURN VALUES"
|
|
\&\fIERR_load_strings()\fR returns no value. \s-1\fIERR_PACK\s0()\fR return the error code.

\&\fIERR_get_next_error_library()\fR returns zero on failure, otherwise a new
