legacy stdc++: Drop standard methods that are implemented in libroot.
sigsetmask is in libbsd.so, so keep the version here. All others can just be dropped as the libroot implementations should suffice.

NAME

basename -- return pointer to last component of a pathname

SYNOPSIS
|

char *basename (const char *name)

DESCRIPTION
|
|
||||||
Given a pointer to a string containing a typical pathname

(/usr/src/cmd/ls/ls.c for example), returns a pointer to the

|
||||||
last component of the pathname ("ls.c" in this case).

Presumes a UNIX style path with UNIX style separators.

NAME

getpagesize -- return the number of bytes in page of memory
|

|
|

SYNOPSIS
|
|
||||||
|
|
||||||
int getpagesize (void)
|
|
||||||
|
|
||||||
DESCRIPTION
|
|
||||||
|
|
||||||
Returns the number of bytes in a page of memory. This is the
|
|
||||||
granularity of many of the system memory management routines.
|
|
||||||
No guarantee is made as to whether or not it is the same as the
|
|
||||||
basic memory management hardware page size.
|
|
||||||
|
|
||||||
BUGS
|
|
||||||
|
|
||||||
Is intended as a reasonable replacement for systems where this
|
|
||||||
is not provided as a system call. The value of 4096 may or may
|
|
||||||
not be correct for the systems where it is returned as the default
|
|
||||||
value.

SYNOPSIS

|
|

static void init_error_tables ();
|
|

|
|
||||||
DESCRIPTION
|
|
||||||
|
|
||||||
Using the error_table, which is initialized at compile time, generate
|
|
||||||
the error_names and the sys_errlist (if needed) tables, which are
|
|
||||||
indexed at runtime by a specific errno value.
|
|
||||||
|
|
||||||
BUGS
|
|
||||||
|
|
||||||
The initialization of the tables may fail under low memory conditions,
|
|
||||||
in which case we don't do anything particularly useful, but we don't
|
|
||||||
bomb either. Who knows, it might succeed at a later point if we free
|
|
||||||
some memory in the meantime. In any case, the other routines know
|
|
||||||
how to deal with lack of a table after trying to initialize it. This
|
|
||||||
may or may not be considered to be a bug, that we don't specifically
|
|
||||||
warn about this particular failure mode.

SYNOPSIS

int errno_max ();

|
|

DESCRIPTION
|
|

|
|
||||||
Returns the maximum errno value for which a corresponding symbolic

name or message is available. Note that in the case where
|
|
||||||
we use the sys_errlist supplied by the system, it is possible for
|
|
||||||
there to be more symbolic names than messages, or vice versa.
|
|
||||||
In fact, the manual page for perror(3C) explicitly warns that one
|
|
||||||
should check the size of the table (sys_nerr) before indexing it,
|
|
||||||
since new error codes may be added to the system before they are
|
|
||||||
added to the table. Thus sys_nerr might be smaller than value
|
|
||||||
implied by the largest errno value defined in <errno.h>.
|
|
||||||
|
|
||||||
We return the maximum value that can be used to obtain a meaningful
|
|
||||||
symbolic name or message.

SYNOPSIS

|
|

char *strerror (int errnoval)
|
|

|
|
||||||
DESCRIPTION
|
|
||||||
|
|
||||||
Maps an errno number to an error message string, the contents of
|
|
||||||
which are implementation defined. On systems which have the external
|
|
||||||
variables sys_nerr and sys_errlist, these strings will be the same
|
|
||||||
as the ones used by perror().
|
|
||||||
|
|
||||||
If the supplied error number is within the valid range of indices
|
|
||||||
for the sys_errlist, but no message is available for the particular
|
|
||||||
error number, then returns the string "Error NUM", where NUM is the
|
|
||||||
error number.
|
|
||||||
|
|
||||||
If the supplied error number is not a valid index into sys_errlist,
|
|
||||||
returns NULL.
|
|
||||||
|
|
||||||
The returned string is only guaranteed to be valid only until the
|
|
||||||
next call to strerror.

NAME
|
|
||||||
|
|
||||||
strerrno -- map an error number to a symbolic name string
|
|
||||||
|
|
||||||
SYNOPSIS
|
|
||||||
|
|
||||||
const char *strerrno (int errnoval)
|
|
||||||
|
|
||||||
DESCRIPTION
|
|
||||||
|
|
||||||
Given an error number returned from a system call (typically
|
|
||||||
returned in errno), returns a pointer to a string containing the
|
|
||||||
symbolic name of that error number, as found in <errno.h>.
|
|
||||||
|
|
||||||
If the supplied error number is within the valid range of indices
|
|
||||||
for symbolic names, but no name is available for the particular
|
|
||||||
error number, then returns the string "Error NUM", where NUM is
|
|
||||||
the error number.
|
|
||||||
|
|
||||||
If the supplied error number is not within the range of valid
|
|
||||||
indices, then returns NULL.
|
|
||||||
|
|
||||||
BUGS
|
|
||||||
|
|
||||||
The contents of the location pointed to are only guaranteed to be
|
|
||||||
valid until the next call to strerrno.
