[PATCH v4 next 10/23] tools/nolibc: Rename the 'errnum' parameter to strerror()

From: david . laight . linux

Date: Mon Mar 02 2026 - 05:24:03 EST


From: David Laight <david.laight.linux@xxxxxxxxx>

Change the parameter variable name from 'errno' to 'errnum'.
Matches any documentation and avoids any issues that might happen
if errno is actually a #define (which is not uncommon).
