cs_register_strfunc: register a string handling function


cs_register_strfunc - register a string handling function


#include <cs/cs.h>

NEOERR *cs_register_strfunc(CSPARSE *parse, char *funcname, CSSTRFUNC str_func);


parse - a pointer to a CSPARSE structure initialized with cs_init()
funcname - the name for the CS function call
Note that registering a duplicate funcname will
raise a NERR_DUPLICATE error
str_func - a CSSTRFUNC not-callback


cs_register_strfunc will register a string function that can be called during CS render. This not-callback is designed to allow for string formating/escaping functions that are not built-in to CS (since CS is not HTML specific, for instance, but it is very useful to have CS have functions for javascript/html/url escaping). Note that we explicitly don't provide any associated data or anything to attempt to keep you from using this as a generic callback... The format of a CSSTRFUNC is: NEOERR * str_func(char *in, char **out); This function should not modify the input string, and should allocate the output string with a libc function. (as we will call free on it)
