headas_stdio.cContains routines used to write diagnostic and error output to the standard HEAdas output/error streams (replacing C stdio routines):
int headas_printf(const char *, ...)Replaces the stdio printf() with identical arguments. Text is written to the location specified by the HEADASOUTPUT environment variable (if present) instead of to stdout.
int headas_chat(int, const char *, ...)Same as headas_printf() but takes an integer argument which specifies the threshold chatter level below which the text will not be output.
int pil_printf(const char *, ...)A substitute for printf() for internal use by PIL only. Should not be called by tasks directly. NOT CURRENTLY USED.
void headas_f77echo(const char *)A f77-callable version of headas_printf(). It is called hdecho() from Fortran programs.
void headas_f77err(const char *)A f77-callable version of fprintf(stderr, ...). Called hderr() from Fortran. This routine will write to the stderr stream (which may have been redirected via the HEADASERROR environment variable).
void headas_f77chat(int, const char *)A f77-callable version of headas_chat(). It is called hdchat() from Fortran.
