The %fgets() function reads characters from the named input stream into var until n-1 characters are read or a new line character is read and transferred to the string.
Syntax
ptr = (char*)%fgets(var, n, (char*)stream) |
Description
The string is terminated with a null character (hexadecimal 00). A string of a size at least equal to n must be assigned to var before the call, otherwise the data is truncated. If less than n-1 bytes are returned, the content of the string beyond is undefined, as is usual in C. No data translation occurs.
The pointer returned has no meaning, except for a null value which indicates an error or that end of file has been encountered.
NOTE |
The null character may have to be removed explicitly, as in the example. |
Example(s)
char line[128] ;* make a buffer pointer=(char*)%fgets(line, 128, (char*)stream) if pointer#0 then line=field(line,char(0),1) print line end |
