Thanks very much for your reply. I have checked that but usleep is called in C++ program, where I want to use usleep command which is there in debian OS.

Thanks,

On Solaris usleep is implemented using SIGALARM. There is no command line implementation. If you need one you need to roll your own.

This works on Solaris:

Code:
#include <stdlib.h>
#include <time.h>

int main( int argc, char **argv )
{
    struct timespec ts;

    if ( argc < 2 ) return( -1 );
    *( ( ldiv_t * ) &ts ) = ldiv( 1000000L * strtol( argv[ 1 ], NULL, 0 ), 1000000000L );
    return( nanosleep( &ts, NULL ) );
}

Yeah, I played some casting games to get around assigning an ldiv_t to a struct timespec. But since they're both "struct { long, long }", it works.
