You need not follow the terms of the GNU General 21# Public License when using or distributing such scripts, even though 22# portions of the text of mkerrcodes.awk appear in them. The GNU 23# General Public License (GPL) does govern all other use of the material 24# that constitutes the mkerrcodes.awk program. 25# 26# Certain portions of the mkerrcodes.awk source text are designed to be 27# copied (in certain cases, depending on the input) into the output of 28# mkerrcodes.awk. We call these the "data" portions. The rest of the 29# mkerrcodes.awk source text consists of comments plus executable code 30# that decides which of the data portions to output in any given case. 31# We call these comments and executable code the "non-data" portions. 32# mkerrcodes.h never copies any of the non-data portions into its output. 33# 34# This special exception to the GPL applies to versions of mkerrcodes.awk 35# released by g10 Code GmbH. When you make and distribute a modified version 36# of mkerrcodes.awk, you may extend this special exception to the GPL to 37# apply to your modified version as well, *unless* your modified version 38# has the potential to copy into its output some of the text that was the 39# non-data portion of the version that you started with. (In other words, 40# unless your change moves or copies text from the non-data portions to the 41# data portions.) If your modification has such potential, you must delete 42# any notice of this special exception to the GPL from your modified version. 43 44# This script outputs an intermediate file that contains the following block 45# for each error value symbol in the input file (example for EINVAL): 46# 47# #ifdef EINVAL 48# EINVAL GPG_ERR_EINVAL 49# #endif 50# 51# The input file is a list of possible system errors in the column errnoidx 52# (defaults to 2). 53# 54# Comments (starting with # and ending at the end of the line) are removed, 55# as is trailing whitespace. 56 57BEGIN { 58 FS="[\t]+"; 59 header = 1; 60 if (errnoidx == 0) 61 errnoidx = 2; 62 63 print "/* Output of mkerrcodes.awk.
