EDT_MSG_INFO_1 (defined as EDTAPP_MSG_INFO_1 | EDTLIB_MSG_INFO_2 |

PDVLIB_MSG_INFO_2)

EDT_MSG_INFO_2 (defined as EDTAPP_MSG_INFO_2 | EDTLIB_MSG_INFO_2 |

PDVLIB_MSG_INFO_2)

Message levels are defined by flag bits, and each bit can be set or cleared individually. So for

example if you want a message handler to be called for fatal and warning application messages

only, you would specify EDTAPP_MSG_FATAL | EDTAPP_MSG_WARNING.

As you can see, the edt and pci dv libraries have their own message flags. These can be turned

on and off from within an application, and also by setting the environment variables

EDTDEBUG and PDVDEBUG, respectively, to values greater than zero.

Application programs would normally specify combinations of either the EDTAPP_MSG_ or

EDT_MSG flags for their messages.

Files

edt_error.h: header file (automatically included if edtinc.h is included)

edt_error.c: message subroutines

The EdtMsgHandler structure is defined in edt_error.h. Application programmers should not access

structure elements directly; instead always go through the error subroutines.

edt_msg_init

Description

Initializes a message handle to defaults. The message file is initialized to stderr. The output subroutine

pointer is set to fprintf (console output). The message level is set to EDT_MSG_WARNING |

EDT_MSG_FATAL.

Syntax

void edt_msg_init(EdtMsgHandler *msg_p)

Arguments

msg_p

pointer to message handler structure to initialize

Return

Void

Example

EdtMsgHandler msg_p;

edt_msg_init(&msg_p);
