Set the given register set.
#include <sys/procfs.h> #define DCMD_PROC_SETREGSET __DIOTF(_DCMD_PROC, __PROC_SUBCMD_PROCFS + 26, procfs_regset)
The arguments to devctl() are:
Argument | Value |
---|---|
filedes | A file descriptor for the process. |
dcmd | DCMD_PROC_SETREGSET |
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 specifies the values to assign to the register set. For example:
procfs_regset regset; regset.id = REGSET_PERFREGS; devctl( fd, DCMD_PROC_SETREGSET, ®set, sizeof(regset), NULL );
To get the given register set, use DCMD_PROC_GETREGSET.
