for (i=o;i<10;i++)
and the cycle will be repeated 10 times.
in UNIX for example I do this:

isaexec
isaexec(3C) Standard C Library Functions isaexec(3C)
NAME
isaexec - invoke isa-specific executable
SYNOPSIS
#include <unistd.h>
int isaexec(const char *path, char *const argv[], char *const envp[]);
DESCRIPTION
The isaexec() function takes the path specified as path and breaks it into directory and file name components. It enquires from the running
system the list of supported instruction set architectures; see isalist(5). The function traverses the list for an executable file in named
subdirectories of the original directory. When such a file is located, execve() is invoked with argv[] and envp[]. See exec(2).
RETURN VALUES
If no file is located, isaexec() returns ENOENT. Other return values are the same as for execve().
EXAMPLES
Example 1: Example of isaexec() function.
On a system whose isalist is
sparcv7 sparc
the program
int
main(int argc, char *argv[], char *envp[])
{
return (isaexec("/bin/thing", argv, envp));
}
will look first for an executable file named /bin/sparcv7/thing, then for an executable file named /bin/sparc/thing. It will invoke
execve() on the first executable file it finds named thing.
On that same system, a program called /u/bin/tofu can cause either /u/bin/sparcv7/tofu or /u/bin/sparc/tofu to be invoked using the follow-
ing code:
int
main(int argc, char *argv[], char *envp[])
{
return (isaexec(getexecname(), argv, envp));
}
