Macro Definition Documentation

#define CONTINUE '\\'

Continuation character.

#define GMX_NO_WCMATCH 1

Return value for gmx_wcmatch() when there is no match.

#define STEPSTRSIZE 22

Minimum size of buffer to pass to gmx_step_str().

#define STRLEN 4096

Standard size for char* string buffers.

Function Documentation

int continuing ( char * s )

Strip trailing spaces and if s ends with a CONTINUE remove that too.

Returns: TRUE if s ends with a CONTINUE, FALSE otherwise.

char* fgets2	(	char *	s,
		int	n,
		FILE *	stream
	)

Reads a line from a stream.

This routine reads a string from stream of max length n, including \0 and zero terminated, without newlines. s should be long enough (>= n)

char* gmx_step_str	(	gmx_int64_t	i,
		char *	buf
	)

Prints a gmx_int64_t value in buf and returns the pointer to buf.

buf should be large enough to contain i: STEPSTRSIZE (22) chars. When multiple gmx_int64_t values are printed in the same printf call, be sure to call gmx_step_str with different buffers.

int gmx_strcasecmp	(	const char *	str1,
		const char *	str2
	)

Case-insensitive strcmp().

int gmx_strcasecmp_min	(	const char *	str1,
		const char *	str2
	)

Version of gmx_strcasecmp() that also ignores '-' and '_'.

char* gmx_strdup ( const char * src )

Creates a duplicate of src.

unsigned int gmx_string_fullhash_func	(	const char *	s,
		unsigned int	hash_init
	)

Return a hash of the string according to Dan J. Bernsteins algorithm.

Parameters

[in]	s	String to calculate hash for.
[in]	hash_init	Initial (or previous) hash value.

Returns: Updated hash value (hash_init combined with string hash).

On the first invocation for a new string, use the constant gmx_string_hash_init for the second argument. If you want to create a hash corresponding to several concatenated strings, provide the returned hash value as hash_init for the second string, etc.

unsigned int gmx_string_hash_func	(	const char *	s,
		unsigned int	hash_init
	)

Return a hash of the string according to Dan J. Bernsteins algorithm.

Parameters

[in]	s	String to calculate hash for.
[in]	hash_init	Initial (or previous) hash value.

Returns: Updated hash value (hash_init combined with string hash).

Identical to gmx_string_fullhash_func, except that this routine only uses characters for which isalnum(c) is true, and all characters are converted to upper case.

int gmx_strncasecmp	(	const char *	str1,
		const char *	str2,
		int	n
	)

Case-insensitive strncmp().

int gmx_strncasecmp_min	(	const char *	str1,
		const char *	str2,
		int	n
	)

Version of gmx_strncasecmp() that also ignores '-' and '_'.

char* gmx_strndup	(	const char *	src,
		int	n
	)

Duplicates first n characters of src.

int gmx_wcmatch	(	const char *	pattern,
		const char *	str
	)

Pattern matching with wildcards.

Parameters

[in]	pattern	Pattern to match against.
[in]	str	String to match.

Returns: 0 on match, GMX_NO_WCMATCH if there is no match.

Matches str against pattern, which may contain * and ? wildcards. All other characters are matched literally. Currently, it is not possible to match literal * or ?.

void ltrim ( char * str )

Remove leading whitespace from a string.

void rtrim ( char * str )

Remove trailing whitespace from a string.

gmx_int64_t str_to_int64_t	(	const char *	str,
		char **	endptr
	)

Convert a string to gmx_int64_t.

This method works as the standard library function strtol(), except that it does not support different bases.

void strip_comment ( char * line )

Remove portion of a line after a ';' comment sign.

void trim ( char * str )

Remove leading and trailing whitespace from a string.

void upstring ( char * str )

Make a string uppercase.

char* wrap_lines	(	const char *	buf,
		int	line_width,
		int	indent,
		gmx_bool	bIndentFirst
	)

Wraps lines, optionally indenting lines.

Wraps lines at linewidth, indenting all following lines by indent spaces. A temp buffer is allocated and returned, which can be disposed of if no longer needed. If bIndentFirst is FALSE, then the first line will not be indented, only the lines that are created due to wapping.
