5.2.55hdfql_variable_get_number

#Syntax

#Description

Get the number of a variable named variable. This refers to the number that was calculated by HDFql and assigned to the variable upon registering it with the function hdfql_variable_register. If variable has never been registered or has been unregistered, an error is returned.

#Parameter(s)

variable – pointer to a variable to get the number (calculated by HDFql) assigned to it.

#Return

int – depending on the success in getting the number assigned to the variable, it can be equal to or greater than zero (i.e. the number assigned to the variable), HDFQL_ERROR_NO_ADDRESS, or HDFQL_ERROR_NOT_REGISTERED.

#Example(s)

// declare variables 
short data0[3];
float data1[5];

// register variable "data0" for subsequent use (by HDFql) 
hdfql_variable_register(data0);

// register variable "data1" for subsequent use (by HDFql) 
hdfql_variable_register(data1);

// display number of variable "data0" (should be "Number of variable is 0") 
printf("Number of variable is %d\n", hdfql_variable_get_number(data0)); 

// display number of variable "data1" (should be "Number of variable is 1") 
printf("Number of variable is %d\n", hdfql_variable_get_number(data1));
