Function Documentation

◆ G_chop()

char* G_chop ( char *  line)

Chop leading and trailing white spaces.

space, \f, \n, \r, \t, \v 

Modified copy of G_squeeze() by RB in March 2000.

Parameters
linebuffer to be worked on
Returns
pointer to string

Referenced by check_create_export_opts(), check_create_import_opts(), check_mapset_in_layer_name(), dig_read_frmt_ascii(), G_str_to_color(), and read_coor().

◆ G_squeeze()

void G_squeeze ( char *  line)

Remove superfluous white space.

Leading and trailing white space is removed from the string line and internal white space which is more than one character is reduced to a single space character. White space here means spaces, tabs, linefeeds, newlines, and formfeeds.

Parameters
[in,out]line
Returns
Pointer to line

Definition at line 441 of file strings.c.

◆ G_store()

char* G_store ( const char *  s)

Copy string to allocated memory.

This routine allocates enough memory to hold the string s, copies s to the allocated memory, and returns a pointer to the allocated memory.

If s is NULL then empty string is returned.

Parameters
sstring
Returns
pointer to newly allocated string

◆ G_store_lower()

char* G_store_lower ( const char *  s)

Copy string to allocated memory and convert copied string to lower case.

This routine allocates enough memory to hold the string s, copies s to the allocated memory, and returns a pointer to the allocated memory.

If s is NULL then empty string is returned.

Parameters
sstring
Returns
pointer to newly allocated lower case string

Definition at line 141 of file strings.c.

◆ G_store_upper()

char* G_store_upper ( const char *  s)

Copy string to allocated memory and convert copied string to upper case.

This routine allocates enough memory to hold the string s, copies s to the allocated memory, and returns a pointer to the allocated memory.

If s is NULL then empty string is returned.

Parameters
sstring
Returns
pointer to newly allocated upper case string

◆ G_str_concat()

char* G_str_concat ( const char **  src_strings,
int  num_strings,
const char *  sep,
int  maxsize 
)

String concatenation.

Concatenates the strings in src_strings, which consists of num_strings number of strings, with the separator sep. The size of the concatenated string is limited by maxsize.

Parameters
src_stringsarray of strings to concatenate
num_stringscount of strings in src_strings
sepseparator string
maxsizemaximum number of characters of returned string
Returns
the concatenated string (allocated)

Definition at line 268 of file strings.c.

◆ G_str_replace()

char* G_str_replace ( const char *  buffer,
const char *  old_str,
const char *  new_str 
)

Replace all occurrences of old_str in buffer with new_str.

Code example:

char *name;
name = G_str_replace ( inbuf, ".exe", "" );
...
G_free (name);
Parameters
bufferinput string buffer
old_strstring to be replaced
new_strnew string
Returns
the newly allocated string, input buffer is unchanged

◆ G_strcasecmp()

int G_strcasecmp ( const char *  x,
const char *  y 
)

String compare ignoring case (upper or lower)

Returning a value that has the same sign as the difference between the first differing pair of characters.

Note: strcasecmp() is affected by the locale (LC_CTYPE), while G_strcasecmp() isn't.
