The corre- + sponding macro is _POSIX_LINK_MAX. + + _PC_MAX_CANON + returns the maximum length of a formatted input + line, where filedes or path must refer to a termi- + nal. The corresponding macro is _POSIX_MAX_CANON. + + _PC_MAX_INPUT + returns the maximum length of an input line, where + filedes or path must refer to a terminal. The cor- + responding macro is _POSIX_MAX_INPUT. + + _PC_NAME_MAX + returns the maximum length of a filename in the + directory path or filedes. the process is allowed + to create. _POSIX_MAX_. + + _PC_PATH_MAX + returns the maximum length of a relative pathname + when path or filedes is the current working direc- + tory. The corresponding macro is _POSIX_PATH_MAX. + + _PC_PIPE_BUF + returns the size of the pipe buffer, where filedes + must refer to a pipe or FIFO and path must refer to + a FIFO.
