strlwr

Converts a string to lower case.

char *strlwr( char *string); 

Return Values

Returns the string in lower case.

Example

In this example, the group name of a Vuser is converted to lower case. However, lr_whoami returns the group name as a static buffer and such buffers cannot be manipulated with. If manipulation is required, a copy of the static buffer must be created.

strdup creates a copy of the static buffer, groupname_static. The characters in the new buffer, groupname, arethen converted to lower case with strlwr.

    #include <string.h>

    int id;
    char * groupname_static, * groupname;

// Get the groupname from VuGen 

    lr_whoami (&id, &groupname_static, NULL);
    lr_output_message ("groupname=%s", groupname_static);

// Make a copy of groupname_static so we can change it

    groupname = (char *)strdup(groupname_static);
    groupname = (char *)strlwr(groupname);
    lr_output_message ("lower case groupname=%s", groupname);
    free(groupname);

Example: Output:
Action.c(8): groupname=None
Action.c(14): lower case groupname=none
