Q3String_Read
You can use the Q3String_Read function to read a string from a file object.
TQ3Status Q3String_Read (
char *data, 
unsigned long *length, 
TQ3FileObject file);
data
On entry, a pointer to a buffer whose length is of size kQ3StringMaximumLength, or NULL. On exit, a pointer to the string read from the specified file object. If this parameter is set to NULL on entry, no string is read, but its length is returned in the length parameter.
length
On exit, the number of characters actually copied into the specified buffer. If data is set to NULL on entry, this parameter returns the length of the string.
file
A file object.

DESCRIPTION
The Q3String_Read function returns, in the data parameter, a pointer to the next string in the file object specified by the file parameter. The string data is 7-bit ASCII, with standard escape sequences for any special characters in the string. The Q3String_Read function also returns, in the length parameter, the length of the string.
