Read the given register set.
#include <sys/procfs.h> #define DCMD_PROC_GETREGSET __DIOTF(_DCMD_PROC, __PROC_SUBCMD_PROCFS + 25, procfs_regset)
The arguments to devctl() are:
Argument | Value |
---|---|
filedes | A file descriptor for the process. |
dcmd | DCMD_PROC_GETREGSET |
dev_data_ptr | A pointer to a procfs_regset structure |
n_bytes | sizeof(procfs_regset) |
dev_info_ptr | NULL |
The argument is a pointer to a procfs_regset structure that's filled in with the required information on return. For example:
procfs_regset regset; regset.id = REGSET_PERFREGS; devctl( fd, DCMD_PROC_GETREGSET, ®set, sizeof(regset), NULL );
To set a given register set, use DCMD_PROC_SETREGSET.
