◆ read_proc_cpuid()

int read_proc_cpuid ( FILE * proc_tid_stat_file )

Get the CPU ID from the /proc/[tid]/stat file.

This function reads the CPU ID from the specified file, which is expected to be in the format of /proc/[tid]/stat. The CPU ID is the 39th field in the file and indicates the CPU number the thread was last executed on.

Parameters

proc_tid_stat_file A file pointer to the /proc/[tid]/stat file.

Returns: The CPU ID the thread was last executed on, or -1 if an error occurs.
