FPUTS fputs(integer file_handle, string buffer [, integer count]) : integer;

Writes from buffer to the file specified by file_handle. The number of characters written

to the file is determined by count if specified; otherwise it is taken to be the string

length of buffer. Returns the number of bytes written to the file. If an invalid file han-

dle is passed, the command is ignored and 0 is returned.

Example

See fcreate command.

FREAD fread(integer file_handle, var string buffer, integer count) : integer;

Reads count bytes from the file specified by file_handle into buffer. If file_handle is

negative, the command is ignored and 0 is returned; otherwise the number of bytes

actually read is returned. If the end of the file is reached, the predefined variable EOF

is set. If an error is encountered while reading, a negative value is returned.

Example

See fcreate command.

FSEEK fseek(integer file_handle, offset, origin) : integer;

File_handle should not be negative. If file_handle is negative or invalid, the command is

ignored and -1 is returned. Offset indicates the number of bytes to move from the

origin specified. Origin can be one of three values: 0 for beginning of file, 1 for current

position, and 2 for end of file. If there is an error, -1 is returned, else the current file

pointer position is returned.

Example

See fcreate command.

FTOA ftoa(real float_no, var string buffer) : integer;

Converts float_no into a sequence of decimal digits and copies it to buffer. If the num-

ber is converted and copied to buffer, 1 is returned; otherwise 0 is returned.

Example

/* This script illustrates the ftoa command. */

proc main;

real x;

string str;

x = 1024.345;

ftoa(x, str);

fdisplay("Number converted is %f, converted string is

➥ ‘%s’^J^M", x, str);

endproc
