void G_free_tokens | ( | char ** | tokens | ) |
Free memory allocated to tokens.
Note: G_free_tokens() must be called when finished with tokens to release memory.

char** G_tokenize | ( | const char * | buf, |
const char * | delim | ||
) |
Tokenize string.
Given a string, buf, turn delimiter, delim, into '\0' (NULL) and place pointers to tokens in tokens. buf must not contain a new line (
). delim may consist of more than one character. G_free_tokens() must be called when finished with tokens to release memory.
Example:
buf | input string |
delim | string delimiter |

char** G_tokenize2 | ( | const char * | buf, |
const char * | delim, | ||
const char * | valchar | ||
) |
Tokenize string.
This function behaves similarly to G_tokenize().
It introduces valchar which defines borders of token. Within token delim is ignored.
Example:
In this example ntok1 will be 4, ntok2 only 3, i.e. { "a", "'b, c'", "d"}
buf | input string |
delim | string delimiter |
valchar | character defining border of token |
