pathconf(2) -- get configurable pathname variables
|
|
The pathconf() and fpathconf() functions provides a method for applications to determine the current value of a configurable system limit or option variable associated with a pathname or file descript... |
|
pipe(2) -- create descriptor pair for interprocess communication
|
|
The pipe() function creates a pipe, which is an object allowing unidirectional data flow, and allocates a pair of file descriptors. The first descriptor connects to the read end of the pipe, and the s... |
|
poll(2) -- synchronous I/O multiplexing
|
|
poll() examines a set of file descriptors to see if some of them are ready for I/O. The fds argument is a pointer to an array of pollfd structures as defined in (shown below). The nfds argume... |
|
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 ... |
|
quotactl(2) -- manipulate filesystem quotas
|
|
The quotactl() call enables, disables and manipulates filesystem quotas. A quota control command given by cmd operates on the given filename path for the given user id. The address of an optional comm... |
|
read(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... |
|
readlink(2) -- read value of a symbolic link
|
|
readlink() places the contents of the symbolic link path in the buffer buf, which has size bufsiz. readlink() does not append a NUL character to buf. |
|
readv(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... |
