.SH "DESCRIPTION"

These functions retrieve information on a SMIng Attribute definition (SMIng).

.PP 

\fBsmiGetAttribute(SmiClass *smiClassPtr, char *name)\fP returns a

pointer to \fBstruct SmiAttribute\fP for the Attribute with the given

\fIname\fP in the given class(\fIsmiClassPtr\fP), or NULL if the

attribute with the given name does not exist.

.PP 

\fBsmiGetFirstAttribute(SmiClass *smiClassPtr)\fP and

\fBsmiGetNextAttribute(SmiAttribute *smiAttributePtr)\fP are used to

iterate through the attributes of the class given by

\fIsmiClassPtr\fP. They return a pointer to \fBstruct SmiAttribute\fP

that represents an attribute or NULL if there are no attributes left

in the class, or error has occurred.

.PP 

\fBsmiGetAttributeParentClass(SmiAttribute *smiAttributePtr)\fP

returns a pointer to a \fBstruct SmiClass\fP, pointing to the parent

class of the given \fIsmiAttributePtr\fP, or NULL if the attribute

does not reference class.  Note that attributes always have either

parent type or parent class.

.PP 

\fBsmiGetAttributeParentType(SmiType *smiAttributePtr)\fP returns a

pointer to a \fBstruct SmiType\fP, pointing to the parent type of the

given \fIsmiAttributePtr\fP, or NULL if the attribute does not

reference type.  Note that attributes always have either parent type

or parent class.

.PP 

\fBsmiGetFirstUniqueAttribute(SmiClass *smiClassPtr)\fP and

\fBsmiGetNextUniqueAttribute(SmiType *smiAttributePtr)\fP are used to

iterate through the unique attributes of the class given by

\fIsmiClassPtr\fP. They return a pointer to \fBstruct SmiAttribute\fP

that represents a unique attribute or NULL if there are no unique

attributes left in the class, or error has occurred. This function

\fBMUST NOT\fP be used for scalar classes, so it should only be called

after \fBisClassScalar()\fP has returned 0.

.PP 

\fBsmiGetAttributeFirstRange(SmiAttribute *smiAttributePtr)\fP, and

\fBsmiGetAttributeNextRange(SmiRange *smiRangePtr)\fP are used to

iterate through ranges that restrict number or octet string types.

Both functions return a pointer to the \fBstruct SmiRange\fP

representing the range, or NULL if there are no more ranges, or error

has occurred.

.PP 

\fBsmiGetAttributeFirstNamedNumber(SmiAttribute *smiAttributePtr)\fP

and \fBsmiGetAttributeNextNamedNumber(SmiNamedNumber

*smiNamedNumberPtr)\fP are used to iterate through named numbers of

bits or enumerations for attributes, which reference types, and to

retrieve the reference restriction of a pointer.  Both functions

return a pointer to the struct SmiNamedNumber representing the named

number, or NULL if there are no named numbers left, or error has

occurred.  \fBsmiGetFirstNamedNumber()\fP can be used to retrieve the

name of the identity that is restricting Pointer type, as it is stored

as the name of the first named number.
