gluIfmember

gluIfmember is a function within the OpenGL Utility Library (GLU) that checks if a given integer value is present within a specified array of integers. It is primarily used for conditional operations or data validation within OpenGL applications. The function takes three arguments: the integer value to search for, a pointer to the beginning of the integer array, and the number of elements in the array. If the value is found within the array, gluIfmember returns a non-zero value, indicating success. If the value is not found, it returns zero. This function simplifies the process of determining membership in an array, allowing developers to avoid writing custom loops for such checks. It is particularly useful when dealing with enumerated types or lists of indices where efficient membership testing is required. The GLU library provides a set of utility routines to assist in writing OpenGL programs, and gluIfmember is one such routine designed to streamline common programming tasks.
