| int | envstr_from_string (struct str *env, const char *s, int overwrite) |
| char ** | envstr_make_array (const struct str *env) |
0 (false) if the function failed due to being unable to allocate memory, and non-zero (true) otherwise. | const char* envstr_find | ( | const struct str * | env, | |
| const char * | var, | |||
| long | len | |||
| ) |
Find the named variable in the environment string.
| int envstr_from_array | ( | struct str * | env, | |
| char ** | array, | |||
| int | overwrite | |||
| ) |
Adds the assignments from the array of pointers to the environment string. The array must be terminated by a NULL pointer, just the same as the standard environ array.
| int envstr_from_string | ( | struct str * | env, | |
| const char * | s, | |||
| int | overwrite | |||
| ) |
Adds the string-based list of assignments to the environment string. Each individual assignment in the list must be ASCII NUL terminated, and the final assignment must be followed by two ASCII NULs.
| const char* envstr_get | ( | const struct str * | env, | |
| const char * | var | |||
| ) |
Get the value of an assignment from an environment string.
| char** envstr_make_array | ( | const struct str * | env | ) |
Make a environ compatable array of pointers to the environment string.
| int envstr_put | ( | struct str * | env, | |
| const char * | asgn, | |||
| int | overwrite | |||
| ) |
Put an assignment, in NAME=value format, into the environment string.
| int envstr_set | ( | struct str * | env, | |
| const char * | var, | |||
| const char * | val, | |||
| int | overwrite | |||
| ) |
Set the named variable to the given value in the environment string.
| void envstr_unset | ( | struct str * | env, | |
| const char * | var | |||
| ) |
Unset the named variable in the environment string.
