So if 'm' is too small, then nothing will be appended. I&...

From: Markus Elfring <elfring at users.sourceforge.net> Date: Mon, 15 Jul 2024 13:36:54 +0200 Single characters should be put into a sequence. Thus use the corresponding function ?seq_putc? for one selected call. This issue was transformed by using the Coccinelle software.

An Intel MIC X100 device is a PCIe form factor add-in coprocessor card based on the Intel Many Integrated Core (MIC) architecture that runs a Linux OS. It is a PCIe endpoint in a platform and therefore implements the three required standard address spaces i.e. configuration, memory and I/O. The host OS loads a device driver as is typical for PCIe devices. The card itself runs a bootstrap after
