- Returns:
- Pointer to result string or null if error in allocating memory 
 
 
Duplicate a string. 
- Parameters:
- 
  
  
- Returns:
- Pointer to cloned string or null if error in allocating memory 
 
 
Convert a colon-separated hexadecimal data into a byte array. 
- Parameters:
- 
  
    | hexstr | String to be parsed |  
 
- Returns:
- Pointer to resulting byte array, or null if no memory available 
 
 
Convert a colon-separated hexadecimal data into a byte array, store result into a previously allocated space. 
- Parameters:
- 
  
    | hexstr | String to be parsed |  | res | Pointer to pre-allocated user space |  | size | Pointer to store lenght of data parsed |  
 
- Returns:
- Pointer to resulting byte array, or null on parse error 
 
 
Check for a null or spaced string. 
- Parameters:
- 
  
  
- Returns:

Splits a string to an array of nelems by using sep as character separator. 
To free() memory used by this call, call free(res[0]); free(res); 
- Parameters:
- 
  
    | str | String to be parsed |  | sep | Character to be used as separator |  | nelems | Number of elements of resulting array |  
 
- Returns:
- res: Pointer to resulting string array, or null if malloc() error 
 
 
Splits a string to an array of nelems by using sep as character separator, using dest as pre-allocated destination memory for the resulting array. 
To free() memory used by this call, just call free result pointer 
- Parameters:
- 
  
    | str | String to be parsed |  | sep | Character to be used as separator |  | nelems | Number of elements of resulting array |  | dst | Char array to store temporary data |  
 
- Returns:
- Pointer to resulting string array, or null if malloc() error 
 
 
Duplicate a string converting all chars to lower-case. 
- Parameters:
- 
  
    | str | String to be cloned & lowercased |  
 
- Returns:
- Pointer to result string or null if error in allocating memory 
 
 
Duplicate a string converting all chars to upper-case. 
- Parameters:

a char is considered space if trues isspace()
- Parameters:
- 
  
  
- Returns:
- Pointer to cloned string with all spaces trimmed or null if error in allocating memory
