# getannotations

Purpose
Retrieve annotations of a model.
Synopsis
`int getannotations(XPRMcontext ctx, const char *ident, const char *prefix, const char **ann, int maxann);`
Arguments

ctx | Mosel's execution context
ident | Symbol to be considered or NULL for global declarations
prefix | Filtering prefix
ann | Array of size maxann where to store the annotations (can be NULL)
maxann | Size of ann (to get up to maxann/2 annotations)

Return value
Size of the array required to get all annotations (two times the number of found annotations).
Further information
1. This function retrieves the annotations associated to the given symbol using a prefix as a filter ( e.g. use "doc." to get all the documentation annotations). The result is stored in the provided array: each annotation occupies 2 entries in the array (the first one for the name of the annotation and the following one for its value).
2. The returned value may exceed maxann (but no more than maxann entries are recorded in the array). To get the required size for ann the function may be called with a NULL array.
