    NAME

    getwd - get current working directory pathname
     
    

    SYNOPSIS

    #include <unistd.h>
    
    char *getwd(char *path_name);
    

     

    DESCRIPTION

    The getwd() function determines an absolute pathname of the current working directory of the calling process, and copies that pathname into the array pointed to by the path_name argument.

    If the length of the pathname of the current working directory is greater than (PATH_MAX + 1) including the null byte, getwd() fails and returns a null pointer.  

    RETURN VALUES

    Upon successful completion, a pointer to the string containing the absolute pathname of the current working directory is returned. Otherwise, getwd() returns a null pointer and the contents of the array pointed to by path_name are undefined.  

    ERRORS

    No errors are defined.  

    USAGE

    For portability to implementations conforming to versions of the X/Open Portability Guide prior to SUS, getcwd(3C) is preferred over this function.
