int SCIPmemccpy	(	char *	dest,
		const char *	src,
		char	stop,
		unsigned int	cnt
	)

copies characters from 'src' to 'dest', copying is stopped when either the 'stop' character is reached or after 'cnt' characters have been copied, whichever comes first.

Note: undefined behaviuor on overlapping arrays

Parameters

dest	destination pointer to copy to
src	source pointer to copy to
stop	character when found stop copying
cnt	maximal number of characters to copy too

void SCIPprintSysError ( const char * message )

prints an error message containing of the given string followed by a string describing the current system error; prefers to use the strerror_r method, which is threadsafe; on systems where this method does not exist, NO_STRERROR_R should be defined (see INSTALL), in this case, srerror is used which is not guaranteed to be threadsafe (on SUN-systems, it actually is)

Parameters

message first part of the error message, e.g. the filename

Parameters

str	string to search
value	pointer to store the parsed value
endptr	pointer to store the final string position if successfully parsed, otherwise `str`

		char	startchar,
		char	endchar,
		char *	token,
		int	size,
		char **	endptr
	)

copies the first size characters between a start and end character of str into token, if no error occured endptr will point to the position after the read part, otherwise it will point to str

Parameters

str	string to search
startchar	character which defines the beginning
endchar	character which defines the ending
token	string to store the copy
size	size of the token char array
endptr	pointer to store the final string position if successfully parsed, otherwise `str`
