NAME

       libmawk_call_function - call an user defined (script) function

SYNOPSIS

       #include <libmawk.h>

       int libmawk_call_function(mawk_state_t *MAWK, const char *fname, CELL *res, const char *argtpes, ...);
       int  libmawk_call_functionp(mawk_state_t  *MAWK,  const char *fname, CELL *res, const char
       *argtpes, void **args);

DESCRIPTION

       The libmawk_call_function() function looks up an user defined awk function called fname  ,
       fills  the  stack  with  arguments converted from the varargs and calls the function.  The
       libmawk_call_functionp() performs the same action but avoids using vararg by requiring  an
       array of generic pointers to the function arguments.

       Argtype is a zero terminated string for both functions, each character corresponding to an
       argument. Type characters are described in libmawk_set_cell() manual page.

       If res is non-NULL, it is cell_destroyed (regardless of errors) and the  return  value  of
       the user function is copied into it. The caller shall run libmawk_cell_destroy on it.

       Argument   m   is  a  libmawk  context  previously  returned  by  libmawk_initialize()  or
       libmawk_initialize_stage3().

RETURN VALUE

       A pointer to the cell returned by the user function. The cell returnedmust be destroyed by
       the application using libmawk_cell_destroy.
