.SH DESCRIPTION
|
|
|
|
The functions of the posix library must be loaded before use with:
|
|
.CS
|
|
(require "posix")
|
|
.CE
|
|
The functions will not be described here completely. For full details
|
|
about a functions and its behaviour, look at the corresponding Unix
|
|
manual page or to the POSIX.1 document.
|
|
|
|
.IP \fIERROR\ MANAGEMENT\fR
|
|
.sp
|
|
.TP
|
|
\fB*errno*\fR
|
|
is a variable which always contains the error number of last
|
|
encountered error. It is equivalent to the errno POSIX.1 variable.
|
|
.TP
|
|
(\fBposix-perror\fR \fIstr\fR)
|
|
produces a message on the standard error output, describing the last
|
|
error encountered during a call to a system or library function. The
|
|
\fIstr\fR parameter is an identifying string which will be printed before
|
|
the error message.
|
|
See \fBperror(3)\fR.
|
|
|
|
.IP \fIFILES\ AND\ DIRECTORIES\fR
|
|
.sp
|
|
.TP
|
|
(\fBposix-stat\fR \fIfilename\fR)
|
|
returns a C structure which contains a description of \fIfilename\fR). This
|
|
structure is not viewable by itself. Use, \fBposix-stat->vector\fR
|
|
to access its content in Scheme.If \fIfilename\fR does not exists, this procedure
|
|
returns \fI#f\fR.
|
|
.TP
|
|
(\fBposix-stat->vector\fR \fIdescr\fR)
|
|
transforms a file description sructure obtained by \fBposix-stat\fR to a Scheme
|
|
vector. The components of the vector are given here with their index:
|
|
.CS
|
|
st_dev (0) st_ino (1)
|
|
st_mode (2) st_nlink (3)
|
|
st_uid (4) st_gid (5)
|
|
st_size (6) st_atime (7)
|
|
st_mtime (8) st_ctime (9)
|
|
.CE
|
|
.DS
|
|
See \fBfstat(2)\fR for details on the semantic of this fields.
|
|
.DE
|
|
.TP
|
|
(\fBposix-access \fIfilename mode\fR)
|
|
checks whether the interpreter is allowed to read, write, execute or test for
|
|
existence of \fIfilename\fR. \fIMode\fR must be one of the following constants:
|
|
\fB|R_OK|\fR, \fB|W_OK|\fR, \fB|X_OK|\fR or \fB|F_OK|\fR.
|
|
If \fIfilename\fR does not exit, this function returns \fB#f\fR.
|
|
See \fBaccess(2)\fR for details.
|
|
.TP
|
|
(\fBposix-pipe\fR)
|
|
returns a pair of Scheme ports associated to a
|
|
pipe inode. If a pipe cannot be created, this function returns
|
|
\fB#f\fR.
