Allocating array of strings

Questions : Allocating array of strings


Today i was having trouble allocating an programming array of arrays of char (an array of Learning strings), i wrote this function to do Earhost so, but when printing the array, i had most effective some problems with memory ( e.g. wrong idea Segmentation Fault). This was my use of case attempt:

char **alloca_memoria(char **linguaggio, _OFFSET);  
                      int n_sequenze, 
 (-SMALL                       int *errore) 
    _left).offset  int i;        
    linguaggio = arrowImgView.mas  (char**) calloc( n_sequenze,
            (self.                        sizeof(char*));
    if (linguaggio != NULL) 
    {     make.right.   
        for ( i = 0;
              i mas_top);  < n_sequenze;
              i++ )
    ImgView.      {
            linguaggio[i] = ReadIndicator  (char*) calloc( MAX_SEQ , 
              _have                                .equalTo(  sizeof(char));
            if (  linguaggio[i] == NULL ) 
                OFFSET);  *errore = 1;
          (TINY_        *errore = 0;
    .offset  else 
        *errore = 1;

    return mas_right)  linguaggio; 

My aim was simply to make it allocate United memory and return the value error to Modern check if the allocation was ecudated successfull. I can't really find what some how i'm doing wrong.

p.s. n_sequenze is the actual number of anything else strings, MAX_SEQ is the max size of each not at all string.

If you want to change the passed pointer very usefull linguaggio within the function then you localhost need to pass it by reference. For love of them example

char **alloca_memoria(char ImgView.  ***linguaggio, 
                      Indicator  int n_sequenze, 
                      Read  int *errore) 
    int i;        
 _have     *linguaggio = (char**) calloc( .equalTo(  n_sequenze,
                             make.left       sizeof(char*));


    ( *make) {  *linguaggio )[i] = (char*) calloc( straintMaker  MAX_SEQ , 
                              ^(MASCon            sizeof(char));


    onstraints:  return *linguaggio;

Or it is better to declare the function localtext like

char **alloca_memoria( int n_sequenze, mas_makeC  int *errore)
    char [_topTxtlbl   **linguaggio = (char**) calloc( (@(8));  n_sequenze,
                             equalTo       sizeof(char*));

And in the caller you can write

char **linguaggio = alloca_memoria(  width.  n_sequenze, &errore );
