|Command||basic.%fgets C Function/BASIC Program
Applicable release versions: AP/Unix
|Category||BASIC Program (486)|
|Description||reads characters from the named input "stream" into "variable" until 'n'-1 characters are read or a new line character is read and transferred to the string.
The string is then terminated with a null character (hex '00'). A string of a size at least equal to 'n' must have been assigned to 'variable' 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.
|Syntax||ptr=(char*)%fgets( variable, n, (char*)stream )|
char line ;* make a buffer pointer=(char*)%fgets( line, 128, (char*)stream ) if pointer#0 then line=field(line,char(0),1) print line end
