Resolving Error Codes
What the heck does "error -19" means? Ever asked yourself or some mailing list this question? Here is a script (I called it errno) to answer this automatically:
#!/bin/sh ERRNO_HEADERS="/usr/include/asm-generic/errno-base.h /usr/include/asm-generic/errno.h" if [ "$1" = "" ]; then ERR="[[:digit:]]+" else ERR=$1 fi cat $ERRNO_HEADERS | grep -E "[[:space:]]$ERR[[:space:]]/"
Now, when you run
you will get this:
#define ENODEV 19 /* No such device */
Additionally, a list of all defined error constants can be retrieved by invoking the script without parameters.
