Detailed Description

Access standard files through character protocol.

This can also be used as an alternative means to access files that manages file pointers.

Constructor & Destructor Documentation

ucc::charfile::charfile ( FILE *  file) [inline]

Construct a charfile from an existing FILE pointer.

Parameters:
fileto use.

Definition at line 534 of file fsys.h.

ucc::charfile::charfile ( const char *  path,
const char *  mode 
)

Construct an open charfile based on a path and mode.

Parameters:
pathof file to open.
modeof file.

Member Function Documentation

void ucc::charfile::open ( const char *  path,
const char *  mode 
)

Open file path.

If a file is already opened, it is closed.

Parameters:
pathof file to open.
modeof file to open.
ucc::charfile::operator bool ( ) [inline]

Test if file is opened.

Returns:
true if opened.

Definition at line 558 of file fsys.h.

bool ucc::charfile::operator! ( ) [inline]

Test if file is not opened.

Returns:
true if not opened.

Definition at line 565 of file fsys.h.

size_t ucc::charfile::put ( const char *  string)

Put a string into the file.

Parameters:
stringto write.
Returns:
number of characters written.
size_t ucc::charfile::readline ( string string)

Read a string of input from the file.

This clears the newline character at the end and has consistent behavior with other ucommon file routines. Because the newline is cleared, the string length may be shorter than the return size.

Parameters:
stringto write.
Returns:
true if data read, 0 if at end of file.
size_t ucc::charfile::readline ( char *  string,
size_t  size 
)

Read a line of input from the file.

This clears the newline character at the end and has consistent behavior with other ucommon file routines. Because the newline is cleared, the string length may be shorter than the return size.

Parameters:
stringto write.
sizeof buffer.
Returns:
true if data read, 0 if at end of file.
