◆ SCIPmemccpy()

SCIP_EXPORT 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

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 behavior on overlapping arrays

Parameters

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

◆ SCIPprintSysError()

SCIP_EXPORT 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

◆ SCIPstrncpy()

SCIP_EXPORT int SCIPstrncpy	(	char *	t,
		const char *	s,
		int	size
	)

safe version of strncpy

Copies string in s to t using at most size-1 nonzero characters (strncpy copies size characters). It always adds a terminating zero char. Does not pad the remaining string with zero characters (unlike strncpy). Returns the number of copied nonzero characters, if the length of s is at most size - 1, and returns size otherwise. Thus, the original string was truncated if the return value is size.

Parameters

t	target string
s	source string
size	maximal size of t

◆ SCIPstrToIntValue()

SCIP_EXPORT SCIP_Bool SCIPstrToIntValue	(	const char *	str,
		int *	value,
		char **	endptr
	)

extract the next token as a integer value if it is one; in case no value is parsed the endptr is set to str

Returns: Returns TRUE if a value could be extracted, otherwise FALSE

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`

◆ SCIPstrToRealValue()

SCIP_EXPORT SCIP_Bool SCIPstrToRealValue	(	const char *	str,
		SCIP_Real *	value,
		char **	endptr
	)

extract the next token as a double value if it is one; in case a value is parsed the endptr is set to str

Returns: Returns TRUE if a value could be extracted, otherwise FALSE

extract the next token as a double value if it is one; in case no value is parsed the endptr is set to str

Returns: Returns TRUE if a value could be extracted, otherwise FALSE

Parameters

str	string to search
value	pointer to store the parsed value

◆ SCIPstrCopySection()

SCIP_EXPORT void SCIPstrCopySection	(	const char *	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 occurred 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`
