char* G_chop | ( | char * | line | ) |
Chop leading and trailing white spaces.

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.
[in,out] | line |
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.
s | string |

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.
s | string |
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.

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.
src_strings | array of strings to concatenate |
num_strings | count of strings in src_strings |
sep | separator string |
maxsize | maximum number of characters of returned string |

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:
buffer | input string buffer |
old_str | string to be replaced |
new_str | new string |

void G_str_to_upper | ( | char * | str | ) |
int G_strcasecmp | ( | const char * | x, |

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.
