This template is used to create pages for $smcFunc functions.

Available parameters:

• function the name of the function (e.g. db_query)
• usage how the function can be used in code with all the parameters available
• description a description of how the function works
• parameters a {{parmdesc}} list of the parameters the function accepts and relative description
• return what the function returns
• notes additional notes if needed
• example an example of how to use the function
• additional fields tree additional fields where is possible to specify the name of the parameter and its content, to be used like in {{parmdesc}}: |name of the field|d1=description of the field
