Scripts
Script tools use outputs from other measurement tools to produce custom measurements.
Similar to other measurement tools, a script tool can output multiple measurement values and decisions. Scripts are added, configured, and removed much like other measurement tools; for more information on this, see Script under Profile Measurement
|
Scripts are limited to 1 megabyte of memory. As a general guideline, calculate the combined memory used by the script given its length in characters and the number and types of variables, structures, and arrays the script uses. |
Script tools use a simplified C-based syntax. The following elements of the C language are supported:
|

|
Function declarations |
Standard C function declarations with argument passed by values. Pointers are not supported. |
