alpha/outb(2) -- Alpha devices I/O ports and memory access functions
|
|
The functions in libalpha give userland programs access to the I/O ports on the OpenBSD/alpha platform. The in*() functions return data read from the specified I/O port. The out*() functions write dat... |

poll(2) -- synchronous I/O multiplexing
|
|
poll() provides a mechanism for multiplexing I/O across a set of file descriptors. It is similar in function to select(2). Unlike select(2), however, it is possible to only pass in data corresponding ... |
|
pread(2) -- read input
|
|
read() attempts to read nbytes of data from the object referenced by the descriptor d into the buffer pointed to by buf. readv() performs the same action, but scatters the input data into the iovcnt b... |
|
preadv(2) -- read input
|
|
read() attempts to read nbytes of data from the object referenced by the descriptor d into the buffer pointed to by buf. readv() performs the same action, but scatters the input data into the iovcnt b... |
|
profil(2) -- control process profiling
|
|
The profil() function enables or disables program counter profiling of the current process. If profiling is enabled, then at every clock tick, the kernel updates an appropriate count in the samples bu... |
|
ptrace(2) -- process tracing and debugging
|
|
ptrace() provides tracing and debugging facilities. It allows one process (the tracing process) to control another (the traced process). Most of the time, the traced process runs normally, but when it... |
|
pwrite(2) -- write output
|
|
write() attempts to write nbytes of data to the object referenced by the descriptor d from the buffer pointed to by buf. writev() performs the same action, but gathers the output data from the iovcnt ... |
|
pwritev(2) -- write output
|
|
write() attempts to write nbytes of data to the object referenced by the descriptor d from the buffer pointed to by buf. writev() performs the same action, but gathers the output data from the iovcnt ... |
|
