public ProgramAttributeInfo GetAttributeInfo(
	int index
)

Parameters

Type: SystemInt32
The index of the attribute variable to be queried.

Return Value

Information about attribute at the given index.

GLExceptionInvalidValue if index is greater than or equal to the number of active attribute variables in program.
Remarks
This method returns information about an active attribute variable in the program object specified by program. The number of active attributes can be obtained by calling ActiveAttributes. A value of 0 for index selects the first active attribute variable. Permissible values for index range from 0 to the number of active attribute variables minus 1.

Attribute variables have arbitrary names and obtain their values through numbered generic vertex attributes. An attribute variable is considered active if it is determined during the link operation that it may be accessed during program execution. Therefore, the program should have previously been linked by calling Link, but it is not necessary for it to have been linked successfully.

This method will return as much information as it can about the specified active attribute variable. If no information is available, the returned name will be an empty string. This situation could occur if this function is called after a link operation that failed.
