const char delim, int
fparseln() function returns a pointer to the next logical line from the stream referenced by stream. This string is null terminated, contains no trailing newline, and is dynamically allocated on each invocation. It is the responsibility of the caller to free the pointer.
By default, if a character is escaped, both it and the preceding escape character will be present in the returned string. Various flags alter this behaviour.
The meaning of the arguments is as follows:
NULL, the length of the string is stored in the memory location referenced by len.
NULL, the value of the memory location to which lineno references is incremented by the number of lines actually read from the file.
NULL, all characters default to values specified below. The contents of delim is as follows:
\’, is used to remove any special meaning from the next character.
\’, is used to indicate that the next line should be concatenated with the current one if this character is the last character on the current line and is not escaped.
#’, if not escaped indicates the beginning of a comment that extends until the end of the current line.
fparseln(). The various flags, which may be OR'ed together, are:
fparseln() function uses
fgetln(3), so all error conditions that
apply to fgetln(3) apply to
fparseln() as well. In addition
fparseln() may set errno to
ENOMEM and return
NULL if it
runs out of memory.
