check existence and attributes of multiple files on unix solaris

i have to parse , and ftp some files, the number of files is unknown but their names are
like *afc*, before starting to work, i want to check if these files exists, and their permisions on the unix system .
can someone help me ? it can be a c source file , or a shell script
i saw this solution,
#include  <stdio.h>
#include  <stdlib.h>
#include <unistd.h>

char *CONFIG_FILE = "user_config";

int main( void )
{
      /* Check for existence */
   if( (access(CONFIG_FILE, F_OK)) != -1 )
   {
      printf( "File exists\n" );

         /* Check for read permission */
      if( (access(CONFIG_FILE, R_OK)) != -1 )
         printf( "File has read permission\n" );

         /* Check for write permission */
         if( (access(CONFIG_FILE, W_OK)) != -1 )
             printf( "File has write permission\n" );
             
         /* Check for write permission */
            if( (access(CONFIG_FILE, X_OK)) != -1 )
                printf( "File has execute permission\n" );
     
   }
   else
   {
      printf( "File does not exists\n" );
   }
}
but i could not understand , where i should write the file names for this program to check, or does it work for multiple files
