# blacs_abort

Aborts all processes.

## Syntax

call blacs_abort( icontxt, errornum )

## Input Parameters

icontxt | INTEGER. Integer handle that indicates the BLACS context to be aborted.
errornum | INTEGER. User-defined integer error number.

## Description

This routine aborts all the BLACS processes, not only those confined to a particular context.

Use blacs_abort to abort all the processes in case of a serious error. Note that both parameters are input, but the routine uses them only in printing out the error message. The context handle passed in is not required to be a valid context handle.
