If the function finds a match, it returns a pointer to a static-duration object that holds the definition associated with the target environment name. Otherwise, it returns a null pointer. Do not alter the value stored in the object. If you call getenv again, the value stored in the object can change. No target environment names are required of all environments.   ]]> /hvaonline/posts/list/35943.html#221253 /hvaonline/posts/list/35943.html#221253 GMT /hvaonline/posts/list/35943.html#221293 /hvaonline/posts/list/35943.html#221293 GMT /*--------------------------------------------------------------------------* Name getenv, _wgetenv - get string from environment Usage char *getenv(const char *envvar); whar_t *_wgetenv(const wchar_t *envvar); Prototype in stdlib.h Description The environment consists of a series of entries that are of the form: name=string\0 The global variable environ points to an array of pointers to these entries.
