.TH GENDERS_GETATTR_ALL 3 "August 2003" "LLNL" "LIBGENDERS"
|
|
.SH NAME
|
|
genders_getattr_all \- get all the attributes stored in a genders file
|
|
.SH SYNOPSIS
|
|
.B #include <genders.h>
|
|
.sp
|
|
.BI "int genders_getattr_all(genders_t handle, char *attrs[], int len);"
|
|
.br
|
|
.SH DESCRIPTION
|
|
\fBgenders_getattr_all()\fR gets all the attributes found in the
|
|
genders file associated with \fIhandle\fR. The attributes are stored
|
|
in the attribute list pointed to by \fIattrs\fR. \fIlen\fR should
|
|
indicate the number of elements that can be stored in the attribute
|
|
list.
|
|
|
|
To avoid passing in a list that is not large enough to store all the
|
|
attributes,
|
|
.BR genders_getnumattrs (3)
|
|
should be used to determine the minimum number of elements \fIattrs\fR
|
|
should be able to store.
|
|
.BR genders_attrlist_create (3)
|
|
could be used to create a list that is guaranteed to be large enough
|
|
to store all attributes.
|
|
.br
|
|
.SH RETURN VALUES
|
|
On success, the number of attributes stored in \fIattrs\fR is
|
|
returned. On error, -1 is returned, and an error code is returned in
|
|
\fIhandle\fR. The error code can be retrieved via
|
|
.BR genders_errnum (3)
|
|
, and a description of the error code can be retrieved via
|
|
.BR genders_strerror (3).
|
|
