Arguments

Name	Comments
instring	The string to evaluate.

The lr_eval_string function returns the input string after evaluating any embedded parameters. If the string argument contains only a parameter, the function returns the current value of the parameter.

Embedded parameters must be in brackets.

Note: lr_eval_string allocates memory internally. The memory is automatically freed at the end of each iteration. You can use lr_eval_string_ext and manually free the memory in each iteration with lr_eval_string_ext_free. Do not, however, use a free statement in your custom code, as this may result in memory corruption.

Return Values

This function returns the value of the specified string or null on error.
