findstrinfile (
    FILE *fp,
    char *strtofind,
    char *strretstr,
    int *iLnNo)

Synopsis

Find's a string inside a text file and reads the line in and sets the file pointer to the beginning of that line. Assumes the line length to be <= 1024 bytes. Returns a pointer to head of the return buffer, and the file postion will be at the start of the found string. If the strretstr param is != NULL then strretstr will contain the line that the search string was found in. Submitted by Scott Beasley jscottb@infoave.com
