tstdio(3) - Linux man page
Name
libtstdio.a - flexible LAM standard I/O package
Synopsis
#include <tstdio.h>
TFILE *tstdin;
TFILE *tstdout;
TFILE *tstderr;
Description
The LAM
libtstdio.a library of C functions provides networked (remote) services
equivalent to those of the
stdio(3) functions. The
tstdio library allows the user to designate the target node to/from which output/input is
directed. The
tstdio functions have the same names and interfaces as their counterpart in
stdio(3), except that the names are prefixed with the
letter 't' (tprintf(), tfopen(), tfclose(), etc.). This allows them to coexist with the
stdio(3V) functions, giving the user the choice to bypass the
LAM I/O functions and access the I/O of the native system.
Files opened using fopen(3), fdopen(3), or freopen(3) are treated as local to the node of the calling process. To open files on the
origin node, from any LAM node, include a 'T' in the type field of the open call. For example:
#include <tstdio.h>
tfopen("/tmp/input", "rT");
By default, functions using tstdout or tstderr direct the streams to the LAM origin node (see getorigin(2)) where the user is assumed to be logged
in.
